Study of semiconductor physics by Ultrafast laser spectroscopy (CAT#: STEM-ST-0330-WXH)

Introduction

Semiconductors are materials which have a conductivity between conductors (generally metals) and nonconductors or insulators (such as most ceramics). Semiconductors can be pure elements, such as silicon or germanium, or compounds such as gallium arsenide or cadmium selenide.




Principle

Ultrafast laser spectroscopy involves studying ultrafast events that take place in a medium using ultrashort pulses and delays for time resolution. It usually involves exciting the medium with one (or more) ultrashort laser pulse(s) and probing it a variable delay later with another.

Applications

study photoinduced dynamical processes in atoms, molecules, nanostructures, and solids
