About

Prof. Srabanti Chowdhury leads the Wide-Bandgap (WBG) Lab at Stanford with a diverse and interdisciplinary group of students and postdocs. The students in the WBG-Lab come from various backgrounds including in Mechanical, Chemical, Materials Science, and Electrical Engineering.

The WBG Lab focuses on wide-bandgap semiconductors such as Gallium Nitride (GaN), Diamond, Gallium Oxide, and others in the family, to deliver innovative device technologies that can provide solutions for the growing demands for efficiency, versatility, compactness, and robustness in electronics. While most of today’s devices and gadgets have been made possible thanks to Silicon (Si), there is an increasing demand for more functionality and a smaller footprint with lower losses, faster speed, and longer lifetime. 

With the WBG materials, we are perfecting heterogeneously integrated solutions with Silicon to offer highly power-dense chips that can save energy consumption. From micro-grid to 5G-and-beyond, WBG materials are shaping the electronics, and we are thrilled to initiate some of those new research directions from our lab.

Our research, addressing some of the imminent global challenges in clean energy and wireless communication, starts with the synthesis of WBG materials. From fabricating devices to our design, characterizing their performance, all the way to demonstrating their potential in circuits, everything is done in the SNF, SNSF, and the measurement labs located at Allen-X. Our goal is to see WBG technology in action, and that’s exactly what our vertically integrated lab offers. We have the unique opportunity to experience the evolution of semiconductor device technology from its start to finish!
