My research focuses on
thin films of organic semiconductors (such as Pentacene) deposited
by High Vacuum Vapor Deposition Technique and their transport properties.
We prepare four-point probe measurements and mobility measurements
for Thin Film Transistor based on Pentacene. We intend to correlate
these measurements with spatially resolved Raman spectra, and investigate
the effect of dopants, impurities and size scaling.
I am also interested in applications of PEEM to semiconductor
devices. We have been using PEEM for the imaging of simple model
devices, searching for basic contrast mechanisms to be used in the
analysis of complex circuits.
