Welcome to the Mukherjee group
in the Materials Department at UCSB!
We are synthesizing 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.
Here, we are working with thin films of the IV-VI (such as
PbSnSe) and the III-V (such as InAs/GaSb) material systems. We
are pushing to directly integrate these thin films on to
functional substrates like silicon and GaAs for hybrid
More recently, we have been interested in the materials
science and engineering aspects of new quantum technologies.

between adsorbate atoms and diamond nitrogen-vacancy centers here
The group has a dedicated IV-VI molecular beam epitaxy (MBE)
tool and uses III-V MBE chambers in the UCSB MBE Lab
and metal-organic CVD tools through our collaborators. In
addition, we work with specialized electron microscopy tools
for in-situ and in-operando study of crystal defects, infrared
optical spectroscopy, and are developing device test chambers
for these very unique thin films. The group benefits from
state-of-the-art materials characterization and fabrication instrumentation
