The Research Intensive Training is a trademark of the Master N². It is specifically dedicated to intensify the formation through research, allowing students to the be continuously immersed in their laboratories in parallel to their courses, during the 2 years of the program.

For this purpose, students can choose up to 3 optional RIT modules of 3 credits each, one in each semester of the program, except for the last semester which is already fully devoted to the master thesis.

A RIT module consists in a part-time internship in a lab of the Grenoble area, representing 1 day each week during a semester. RIT modules are thought to be performed in the same research teams on the same research project, allowing students to achieve a substantial research contribution with possibly a publication during their master.  However students can also change lab, project or research team, with the agreement of their program coordinator, in order to get a broader scientific experience. Students can then discover ongoing research in nanosciences not only in their specialization but also in sister disciplines. It also offers them an opportunity to initiate connections in view of finding their master thesis subject.

RIT modules are evaluated through a short report followed by an oral examination, in which students expose their research objectives, implementation, and results, and answer to the questions of the jury. RIT performed in the second semester of the first year can be evaluated together with the compulsory M1 research internship.

Admission to Research Intensive Training modules requires the agreement of the school-year coordinator.  In M1, the training is fully appropriate to students having completed a 4-years bachelor of science, or engineering, however 3-year's bachelors who have excellent academic results can also be admitted to the RIT.

In the context of intensive research on post-CMOS electronics, a new families of nano-materials has opened new avenues in different fields, including optoelectronics and quantum information. These low-dimensional systems are a new playground to understand the interactions between elementary excitations, electron-phonon and phonon-phonon, which play a major role in the behavior of electron transport and heat at this nanoscale. For example, the reduction of dimensionality in the case of graphene has made the adiabatic approximation obsolete. Thus, the electron-phonon coupling is so strong that the optical phonons can be modulated by an external electric field but also as has been recently shown by an optical grid.

The important advances in the control of graphene electronic properties, open the way to new two-dimensional materials. Thus, monolayers of Dichalcogenides of Transition Metals such as MoS₂ (MoSe₂, WS₂, WSe₂, …etc.) have appeared very recently as promising nanostructures for applications in both the field of optics and electronics. We will discuss the growth of such materials including the fabrication of heterostructures based on graphene (semi-metal), boron nitride (insulator) and MoS₂ (semiconductor) and their physical properties. Indeed marrying different 2D systems can take advantage of the properties of each part and more since the resulting hybrid is more than the sum of its parts.

This lecture will give an overview of the physical properties of graphene on the one hand, new 2D semiconductors like MoS₂ on the other hand and will open on the heterostructures. We will discuss their growth, band structure, phonons, electron-phonon coupling, excitons in MoS₂, the spin / valley polarization but also the prototype components (transistor, photodiode, LED ...) based on this new class of materials.

Goal: This course will give a general view on the topic of photon or wave interactions with matter at various energy scales and length scales.

Content
In the first part, we will focus on the problem of the propagation of an electromagnetic wave when the wavelength is large (UV, optical, etc.) compared to the interatomic distances. The problem of polarization of the medium in metals and in semiconductors (Drude, Lorentz, interband, etc.) will be discussed and surface plasmons which are longitudinal excitations at the SC-metal interface will be treated. Finally, we will discuss how we can localize light on length scales smaller than the wavelength (e.g. nanoparticles). This part will be completed by a section on the Kramers-Kronig relations that link reflectance to absorption. The second part of the course will focus on phenomena where the incident wavelength is much smaller, such that matter can be resolved to atomic scales. The problem of structure factors and their interpretation in terms of correlation functions (neutrons, X, etc.) will be discussed.

The Second year Research Training can take two different forms:

- 10 half-days spent in identified labs on recurrent subjects proposed by the coordinator of the teaching unit ;

- a part-time internship in a lab of the Grenoble area, representing more or less 1 day each week during a semester. In can be on the same subject as the M1 internships and/or of the future M2 internships, allowing a continuous immersion in a laboratory on a given for the whole duration of the master program. Students joining the program in M2 can also follow this program but they must readily find a welcoming lab by themselves prior to their arrival in Grenoble or at the very beginning of the academic year.

In both cases, the module is evaluated through a short report followed by an oral examination, in which students expose their research objectives, implementation, and results, and answer to the questions of the jury.

This course is at the crossroad between two important scientific and technological domains: energy and nanomaterials. Indeed both domains are rich in innovations, challenges and opportunities. For instance, among other sustainable green energy technologies, solar energy has been and is still developed to offer an alternative to fossil fuel energy, with efforts devoted for instance to cost reduction, efficiency improvement and use of abundant materials. We will see how nanomaterials can help improving performance of devices related to energy, and thus in very different domains (solar energy, building, energy storage…). The course will first deal with the contexts linked with energies and nanomaterials. The synthesis, characterization and main properties of nanomaterials will be presented. Applications will deal with: solar energy and nanomaterials, other energy production and nanomaterials, energy storage and finally nanomaterials and energy in buildings.

Content
This course will be presented by different scientists aiming at presenting physical and chemical aspects of nanomaterials, as well as with complementary approaches such as fundamental, experimental and applied ones. In addition to basic concepts many illustrations and challenges still persisting will be briefly presented during the whole course.

This second part describes the devices that are currently used and developed to sustain Moore’s law: it spans the transistor technologies from bulk, to Finfet and FDSOI with their pros and cons and how they are manufactured, with a quick overview of the semiconductor industry players. It also describes the evolution of Moore’s law and how it has moved from transistor to memory centric after having hit the limits of scaling, we have switched from dimensions scaling only to the introduction of new computing paradigms such as in memory computing to sustain the performance improvement of integrated circuits. Finally, it screens all the devices that are developed in order to overcome scaled transistors limitations with a strong emphasis on silicium spin qubits seen as a major contender to enable quantum computing.

The Master's thesis project is a personal research work curried out during the second year of the master, to which the entire spring semester is devoted. For this purpose students perform an internship of minimum 5 months in a research team.  As a graduate student, you will be responsible for a specific project in nanosciences under the guidance of a thesis supervisor. You will have the opportunity to collaborate with PhD students, post-docs, full-position researchers and professors.

The master thesis is evaluated by a thesis manuscript and a public defense. In this manuscript the student is expected to:

• Provide a clear definition of the scientific or technological problem addressed
• Demonstrate mastery of the scientific literature related to the problem
• Describe the chosen approach to solve the problem, and present the results obtained
• Perform a scientific discussion of these results in relation to the state of the art

The public defense is held in front of a jury, which evaluates the completion of the above expectations through the student presentation and answers to questions. The defense also prepares students to the concourses held by the Grenoble's doctoral schools for the attribution of UGA funded PhD's positions.

According to the french law, the research institute will pay you a "gratification" of 530€/month during your research internship, for a maximum duration of 6 months in a given school year.
