Kinetics of photo-dissolution within Ag/As2S3 heterostructure
Pritam Khan, Yinsheng Xu, William Leon +4
Chalcogenide glass-silver heterostructures are candidates for photoresist and diffractive optical applications. To optimize their processing, we report the kinetics of Ag photo-dis…
Ultrafast light-induced softening of chalcogenide thin films above the rigidity percolation transition
Pritam Khan, Rajesh Kumar Yadav, K. V. Adarsh
Little is known about the role of network rigidity in light-induced structural rearrangements in network glasses due to a lack of supporting experiments and theories. In this repor…
Excitation of coherent optical phonons in iron garnet by femtosecond laser pulses
Pritam Khan, Masataka Kanamaru, Wei-Hung Hsu +4
We employed femtosecond pump probe technique to investigate the dynamics of coherent optical phonons in iron garnet. A phenomenological symmetry-based consideration reveals that os…
Investigation of Temperature Dependent Optical Modes in GexAs35-xSe65 Thin Films: Structure Specific Raman, FIR and Optical Absorption Spectroscopy
Pritam Khan, Arinjoy Bhattacharya, Abin Joshy +3
In this article, we present a comprehensive study of temperature and composition dependent Raman spectroscopy of GexAs35-xSe65 thin films to understand different structural units r…
