Recognition

His work received a number of prestigious awards including one from the president of United States Donald Trump Presidential Early Career Award for Scientists and Engineers[1][7] given to outstanding scientists and engineers in the U.S by the White House. His work has resulted in prestigious National Science Foundation CAREER Award[2][3] and Ten Outstanding Young Persons of the World award. In 2019 and 2020, his work has seen him identified as one of the most influential researchers over the past decade by Clarivate Analytics and Web of Science.[4][5][8] Google scholar statistics independently has identified him as one of the top 10 researchers in the world in the area of quantum materials[9] and top 50 in two-dimensional materials.[10]

Research and career

He studied materials physics at the University of Florida working with Prof. Dr. Arthur F. Hebard[11] and postdoctoral fellowship at the materials science and engineering at the University of California, Berkeley and Stanford.[12] His notable and most cited work includes the discovery of exciton complexes in 2D crystals, defects engineering in 2D materials, 2D superlattices, graphene based high-power devices,[13] and graphene solar cells.[14][15] He is known for establishing the current transport at these two-dimensional interfaces[16] and the discovery of new class of 2D anisotropic semiconductor, Rhenium disulfide (ReS2).[17] Other seminal discoveries and contributions to the field include the defects engineering in 2D quantum materials,[18] 2D alloying, van der Waals epitaxy growth of quantum materials, 2D anisotropic materials, the discovery of Moire excitons in 2Ds,[19] band alignment models in 2D heterojunctions, the discovery of quintons,[20] 2D phase change alloys, the discovery of bright/dark excitons, and the engineering of 2D anisotropic materials.[21]
