Time Resolved Spectroscopy in InAs and InSb based Narrow-Gap Semiconductors
… it is crucial to probe carrier dynamics in semiconductors on femtosecond timescales. Time resolved spectroscopy is an excellent tool to probe the relaxation dynamics of photoexcited carriers; where after the initial photoexcitation, the nonequilibrium population of electrons and holes relax …

Probe of Coherent and Quantum States in Narrow-Gap Based Semiconductors in the Presence of Strong Spin-Orbit Coupling
The goal of this project was to study some unexplored optical and magneto-optical properties of the newest member of III-V ferromagnetic structures, InMnSb, as well as InSb films and InSb/AlInSb quantum wells. The emphasis was on dynamical aspects such as charge and spin dynamics in order to …

Laser beam induced current studies of Hg1-xCdxTe photodiodes
Laser-beam-induced-current (LBIC) is being investigated as a combined electro-optical (EO) alternative to individual electrical and optical based measurements of p-n junction photodiodes. The technique is non-destructive and employs a focused low-power laser beam that is scanned across the …
