Welcome to the Mukherjee group in the Materials Department at UCSB!

We are interested in the synthesis of narrow band gap semiconductors and topological insulators that emit and detect light in the infrared. This would enable better materials for environmental monitoring, quantum computing, manufacturing, and defense. To this end, thin films of alloys of the IV-VI (such as PbSnSe) and the III-V (such as InAs/GaSb) material systems are of great interest to us. We are pushing to directly integrate these thin films on to  functional substrates like silicon and GaAs for hybrid circuits.

The group has a dedicated IV-VI molecular beam epitaxy (MBE) tool as well as access to III-V MBE chambers in the UCSB MBE Lab and metal-organic CVD tools through our collaborators. In addition, we are setting up specialized electron microscopy tools for in-situ and in-operando study of crystal defects, infrared optical spectroscopy, and device test chambers for these very unique thin films. The group benefits from state-of-the-art materials characterization and fabrication instrumentation at UCSB.
