Tailoring between network rigidity and nanosecond transient absorption in a-GexAs35-xSe65 thin films
Pritam Khan, Tarun Saxena, K. V. Adarsh
In this letter, we report the first observation of dramatic decrease in nanosecond (ns) pulsed laser induced transient absorption (TA) in a-GexAs35-xSe65 thin films by tuning the a…
Nanosecond light induced, thermally tunable transient dual absorption bands in a-Ge5As30Se65 thin film
Pritam Khan, Tarun Saxena, K. V. Adarsh
In this article, we report the first observation of nanosecond laser induced transient dual absorption bands, one in the bandgap (TA1) and another in the sub-bandgap (TA2) regions…
Coexistence of fast photodarkening and slow photobleaching in Ge19As21Se60 thin films
Pritam Khan, A. R. Barik, E. M. Vinod +3
We experimentally demonstrate the coexistence of two opposite photo-effects, viz. fast photodarkening (PD) and slow photobleaching (PB) in Ge19As21Se60 thin films, when illuminated…
Role of Ge:As ratio in controlling the light-induced response of a-GexAs35-xSe65 thin films
Pritam Khan, H. Jain, K. V. Adarsh
In this paper, we present interesting results on the quantification of photodarkening (PD), photobleaching (PB) and transient PD (TPD) in a- GexAs35-xSe65 thin films as a function…
