Biography

Dr. Bhubesh Chander Joshi joined the Department of Physics and Materials Science & Engineering at Jaypee Institute of Information Technology (JIIT), Noida, in July 2011. He holds a master’s degree in physics with a specialization in Electronics from Kumaun University, Nainital, in 2004, and a Ph.D. degree in Electronic Science from CSIR-CEERI Pilani and Kurukshetra University, Kurukshetra, in 2010.

Before joining JIIT, Dr. Joshi was actively involved in research at CSIR–Central Electronics Engineering Research Institute (CEERI), Pilani, where he worked from 2006 to 2011 as CSIR-JRF, SRF, and RA on design and development of semiconductor devices, including modelling, growth, and fabrication of high-performance GaN-based optoelectronic structures. Additionally, in 2005-06, he worked as a DST-JRF on a project related to Active Tectonics in the Sikkim-Darjeeling Himalayas, where he was involved in seismic activity monitoring, landslide surveillance, GPS station maintenance, 3D topographical map generation, and GPS data processing using the GAMIT/GLOBK software.

His research experience spans the design and analysis of FinFET, GaN HEMTs, LEDs, solar cells, power electronics, and optoelectronics. At JIIT, he has been involved in teaching postgraduate and undergraduate courses in Basic Physics, Electronics, Solid-State Devices, and Photovoltaics. He has successfully guided several M. Tech and Ph.D. students. Dr. Joshi’s research interests include the development of metal oxide-based heterostructures, flexible UV sensors, thermoelectric materials, energy-efficient materials, and the reliability analysis of X and Y class capacitors under Indian environmental conditions. He has published over 25 papers in reputable international journals and has presented his work at numerous national and international conferences.

Research Highlights

Dr. Bhubesh Chander Joshi’s research focuses on the design, development, and characterization of advanced semiconductor devices and materials for optoelectronic and energy applications. His core expertise lies in wide-bandgap semiconductors, such as GaN and ZnO, used in high-power, high-frequency, and UV-sensing devices.

At JIIT, Dr. Joshi has worked extensively on metal oxides, heterostructure engineering, laser ablation, and sol-gel deposition of thin films, as well as FinFETs, solar cells, and thermoelectric materials. His recent work investigates Cu- and Ni-doped ZnO films and ZnO/CuZnO heterostructures for optoelectronic applications, with a particular focus on band alignment using synchrotron-based techniques. These studies offer profound knowledge about the local electronic structure and interface properties that are essential for high-efficiency devices.

Dr. Joshi also explores advanced CMOS device architectures, such as FinFET, Gate-All-Around (GAA), and multi-gate transistors, to address power dissipation, heating, noise, and scaling issues. He has published impactful studies on thermal management and performance optimization in 3D nano transistors. Additionally, he is investigating the environmental reliability of Class Y capacitors under Indian ambient conditions to develop more robust passive components for power electronics in humid and thermally stressful environments.

Beyond academic research, Dr. Joshi has worked on various small electronics projects, including power supply design, IoT-based home automation systems, and the development of a smart soldering station using a JBC C210 tip. He has strong hands-on experience with electronic devices and components, including SMD and BGA-level assembly and rework.
