Current Research Interests:
Professor and his colleagues at the University of
California, Santa Barbara have done pioneering research in the area of
semiconducting and metallic polymers. This class of novel materials has
the electrical and optical properties of semiconductors and metals in
combination with the processing advantages and mechanical properties of
polymers. His current research interests lie in the area of transport in
semiconducting polymers and light emission from semiconducting polymers
(both photoluminescence and electroluminescence). His research group
focuses on issues related to the fundamental electronic structure of this
novel class of materials and carries out studies of light emitting diodes
(LEDs), light-emitting electrochemical cells (LECs), and lasers, all
fabricated from semiconducting (conjugated) polymers. Experimental
facilities provide the capability for a broad range of spectroscopic
studies (including ultrafast, fs, time resolved spectroscopy),
quantitative measurement of photoluminescence and electroluminescence
quantum efficiencies, optical gain/loss of conjugated polymer/oligomer
laser materials, and photoconductivity (steady state and time resolved
with sub-ns time resolution). |
