Paper Abstract
Many of the conducting polymers though having good material property are not solution
processable. Hence an alternate method of fabrication of film by pulsed laser deposition, was explored
in this work. PDTCPA, a donor- acceptor- donor type of polymer having absorption from 900 nm to
300 nm was deposited by both UV and IR laser to understand the effect of deposition parameters on the
film quality. It was observed that the laser ablation of PDTCPA doesn’t alter its chemical structure
hence retaining the chemical integrity of the polymer. Microscopic studies of the ablated film shows
that the IR laser ablated films were particulate in nature while UV laser ablated films are deposited as
smooth continuous layer. The morphology of the film influences its electrical characteristics as
current- voltage characteristic of these films shows that films deposited by UV laser are p rectifying
while those by IR laser are more of resistor in nature.
