Dr. Abhay A. Sagade

Ph.D.

Research Associate Professor

Welcome to the Laboratory for Advanced Nanoelectronic Devices at SRM Research Institute. We are involved in materials innovation for enabling new device structures and concepts. We study a wide range of electronic materials at nanoscale in both planar and 3D geometries.  Exotic schemes of manipulating, processing, and engineering materials at low-dimensions are explored for new functionalities and properties. We are highly interdisciplinary in working covering experimental semiconductor Physics, Electrical Engineering, Materials Science, and Chemistry. All these activities are aimed in innovative manufacturing technologies for large-area nano-electronics, where the device and ultimately system level performance is investigated.
 
Open positions:  We are currently looking for talented and motivated research scholars to join the group. For more details see 'opportunities'.
