Krishna Sharma becomes first Sikkimese to earn PhD in Semiconductor Quantum Plasma Physics

In a proud moment for Sikkim, Krishna Sharma from Assam Lingzey has become the first person from the state to earn a PhD in the field of Semiconductor Quantum Plasma Physics. He successfully defended his thesis on April 29, 2025, at the Department of Physics, Sikkim Manipal Institute of Technology (SMIT), under Sikkim Manipal University (SMU).

His research, titled “Instabilities in Semiconductor Quantum Plasma in Presence of Electric and Magnetic Fields”, was guided by Dr. Utpal Deka, Professor of Physics at SMIT, and co-supervised by Dr. Rustam Ali from the Department of Mathematics. The PhD viva was evaluated by Professor Pralay Kumar Karmakar of Tezpur University.

Krishna’s doctoral work explored how quantum effects like spin forces, exchange-correlation potential, and particle degeneracy impact wave behaviour in semiconductor plasmas. His findings, including the identification of “stability gaps” due to temperature and nanoparticle implantation, may benefit future technologies in quantum devices, sensors, antennas, and semiconductor components.

A former student of Assam Lingzey Government Senior Secondary School and TNSS School Gangtok, Krishna went on to earn Gold Medals in both his B.Sc. (NBBGC Tadong) and M.Sc. (SMIT). He also qualified prestigious exams including UGC-NET (JRF), SLET, and GATE.

Currently serving as Assistant Professor in the Physics Department at NBBGC Tadong, he continues to mentor young minds in science. On his PhD achievement, Krishna expressed gratitude to his supervisors, SMIT faculty, the university administration, the Education Department, and colleagues from NBBGC. Most importantly, he dedicated the milestone to the love and support of his family.
