Dr. Arup Ratan Pal

Our research at Plasma Nanotechnology Laboratory is focussed on the synthesis of nanomaterials by plasma based processes with the specific aim of material synthesis suitable for advanced electronic, optoelectronic and bioelectronic devices.

We develop films of plasmonic materials, conducting polymers, nanocomposites of conducting polymers with metal/metal oxide nanoparticles and with some inorganic nanocrystals by solvent free as well as water free plasma based processes, in significantly less numbers of process steps.

We are also working on preparing carbon nanomaterials e.g. nanofibers, nanotubes and graphene at low temperatures suitable for fabrication of electronic and optoelectronic devices.

In the device development area we mainly work on fabrication of plasmonic photo-detectors, solar cells and photo-transistors using the nanomaterials developed by plasma processes.

We put strong emphasis on understanding the basic material properties and charge transport properties for development of advanced devices.
