About


Prof. Vikram Kumar is well known in the area of semiconductor materials characterization and device technology.
His early work on ultra thin oxide MOS structures is cited widely. His extensive work towards the understanding of electronic defects and interface states in silicon, III-V and II-VI semiconductors lead to the prestigious Shanti Swarup Bhatnagar Award in 1992.
As the Director of the Solid State Physics Laboratory, he has contributed towards the development of technology of materials and devices some of which reached production stage. His team developed the technology of 0.7m gate ion implanted MESFET and 0.5m pseudomorphic HEMT using MBE grown strained layer AlGaAs/InGaAs/GaAs structures. He led the team for setting up GaAs Enabling Technology Centre (GAETEC) foundry for pilot production of monolithic microwave integrated circuits (MMIC) that is supplying devices to various users including defence and space. His team has also developed the technology for growth of single crystals of CdZnTe and GaAs and supplied device quality wafers. He also contributed to the development HgCdTe based PV and PC infra-red detectors. Under his directorship, NPL underwent international peer review to fulfil the requirements of BIPM mutual recognition arrangement (MRA). Kumar is currently working in the area of polymer electronics. At NPL he initiated programmes on silicon and organic solar cells. In particular, he has been modelling carrier transport in organic materials.
He has been contributing to the development of science and technology in India as member of several nationally important committees. He played a key role in starting the National Programme on Smart Materials, and as Chairman of the committee for development of devices, has guided the development of MEMS technology in India. He is a fellow of the NASc, INAE and IETE in addition to being a member of several professional societies.
