Reducing the bandgap energy via doping process in lead-free thin film nanocomposites
Padmaja Guggilla
Alabama A&M University, USA
There are numerous applications for the pyroelectric composite films in the medical field, military field and environmental
applications field. The main focus of this research is to fabricate the higher efficiency thin films that are flexible like the polymers.
PVDF is ideal when it comes to making detectors as they are flexible; possess high pyroelectric current and resistance, low dielectric
constant and density. Pure PVDF and PVDF films doped with CNT and MWCNT, PVDF: LiTaO3, PVDF:LiTaO3 films doped with
MWCNT thin films were fabricated using the solution casting technique. Evaluated the deposited films’ electrical, optical and
structural properties using SEM, FTIR Spectroscopy, UV-Vis Spectroscopy, and Raman Spectrum. Results show that doping with
CNT and MWCNT is enhancing the key characteristics that are beneficial for the optical devices industry.
