CHHOTRAI SOREN

Mr. Chhotrai Soren is currently pursuing his PhD degree from the Department of Materials Science and Engineering at IIT Delhi. His research utilizes the interdisciplinary knowledge of material engineering, electronic device fabrication, and device testing for neuromorphic applications. During his Ph.D. tenure, he has optimized the growth of thin film oxides using the Pulsed Laser Deposition Method, gain expertise in lithography and packaging of electronic devices. 

Previously, during his M.Tech., he worked on Screen Printed Thick film sensor electrodes for Electrochemical Sensing. His work involved studying the physical properties of the screen with the variation in elastic property, mesh count and open area of mesh, affecting the final result of the device during fabrication. Also physiochemical factors such as viscosity of the medium, thermal conductivity of the substrate and crystalline structure affect the performance of the fabricated device. His work also involved the packaging of sensor electrode through Die bonding and study of solder joint formed over the electrode structures using lead free solder paste (Sn99Ag0.3Cu0.7).
