(a) Significant contributions to science and/ or technology development by the nominee based on the work done in India during most part of last 5 years:
The main emphasis of the Prof. Mandar Deshmukh’s work during last five years is to study mesoscopic systems, particularly 2D materials that are of great current interest from the fundamental physics as well as applications angle. Mandar’s group has developed novel techniques and analysis tools that allow studies of nanoscale physics, which are crucial in these aspects. Mandar focused broadly on probing two properties – namely electronic and elastic response of mesoscopic systems. They have a very close connection and so a better understanding of these two properties is the key for the advancement of knowledge in this field. Main conclusions on selected materials are highlighted below.  Studies of electronic properties: Graphene: Recently Mandar has studied tunable superlattice in graphene - this unique experiment realizes a Kronig-Penny model for Dirac electrons. This tunable superlattice modifies the bandstructure continuously to realize new Dirac cones in the band structure. (Nano Lett., 13, 3990 (2013); 16 citations/Google Scholar). His work in the quantum Hall regime offers insight into edge state equilibration. In earlier experiments on graphene Mandar has studied the properties of Dirac electrons in graphene in the quantum Hall regime to understand non-equilibrium breakdown of the quantum Hall state. (Phys. Rev. B 80, 081404(R) (2009); 20 citations/Google Scholar). Semiconducting nanowires: Semiconducting nanowires are platforms for studying tunable spin transport and Mandar’s work has explored how the spin-orbit interaction can be tuned in InAs nanowires (Phys. Rev. B 79, 121311(R), 2009; 39 citations/Google Scholar). Realizing new geometries of field effect transistors can improve the ability of the switching characteristics. Mandar made a key innovation by realizing a wrapgate transistor with InAs nanowires (Appl. Phys. Lett. 99, 173101 (2011); 12 citations/Google Scholar). Correlated systems: A system that Mandar has explored in great detail is the metal insulator transition (MIT) in VO2. Mandar has tried to answer the question – is it possible to tune the MIT by doping the system electrostatically? They show that this is indeed possible. ((Nano Lett. 13, 4685 (2013) (3 citations/Google Scholar); Appl. Phys. Lett. 99, 062114 (2011) (21 citations/Google Scholar); Nano Lett., 2012, 12, 6272(10 citations/Google Scholar).  Studies of elastic properties: One of the key components of Mandar’s research is to answer the question – do elastic properties of nanoscale systems across phase transitions get significantly modified because of the modification of the electron-phonon coupling? His work shows that the plasmons associated with the CDW can modify the properties in nanoscale CDW system. (Physical Review Letters 110, 166403 (2013) (2 citations/Google Scholar); Physical Review B 82, 155432 (2010) (8 Citations/Google Scholar). Using high frequency techniques, Mandar led the experiments that studied the elastic properties of graphene using nanomechanical resonators. He measured the negative thermal expansion coefficient of graphene from 300K-30K (Nanotechnology 21, 165204 (2010); 90 citations/Google Scholar). The innovation to use nanomechanics to study correlated systems and elastic properties is unique on a global scale. Summarizing, Professor Mandar Deshmukh has 35 publications to his credit of which 24 are from his independent research group after he joined TIFR in India.
(b) Impact of the contributions in the field concerned:
Mandar’s work has been published in high impact journals like Nano Letters (Impact factor 13; 5 papers in the last two years year), and Physical Review Letters and has been recognized for its high quality in many ways. It is to be noted that his work on nanowire transistors has been featured in Nature in the News and Views (Nature 481, 152 (2012).) where the work is judged by the article to have the potential to change the way nanowire transistors are made in the future. In addition, the very fact that he received very prestigious international awards/fellowships already, in particular IBM Faculty Award as recognized by an international industry, speaks in favor of technological impact his basic research work would have. Finally, he has a total 1420 of citations and his H-index is 16 (based on Google Scholar), and this remarkable citation endorses impactful nature of his scientific output.
