Why I study Physics? or Science?
A perspective of the Universe that is in plain-sight appears more fascinating. Everything has a facade of simplicity, which is shredded by the complexity unveiled by science, creating a thing of beauty.
And who is better at explaining this than Prof Feynman...
Electrical characterization of PLD grown BTO/TiN
Electrical characterization of PLD grown BTO/TiN
BTO/TiN is a high-k dielectric, which also showcases ferroelectric behavior. Using cryogenic probe stations and ferroelectric measurement tools, we showcased polarization loops and capacitance curves and analyzed the response of defects in the films.

Fabrication of interdigitated back contact (IBC) solar cells for Singlet Fission
Utilizing the nanofabrication facility at Center for Nano Science and Engineering (CeNSE), we tried to demonstrate the Singlet Fission as a way to go beyond the Schokkley Quisser limit of solar cells by transferring excitons generated in organic chromophore (tetracene) into the IBC solar cell.
