Observation of the fundamental exciton in low-temperature grown GaAs using four-wave mixing spectroscopy
(2013-12-16)
The nonlinear optical response of low-temperature (LT) grown GaAs were studied
using four-wave mixing techniques. Through measurements of the four-wave mixing
response as a function of pulse delay and photon energy, a ...
Transient Four-Wave Mixing Studies of GaAs, Low-Temperature-Grown GaAs, and CH3NH3PbI3
(2017-12-19)
Understanding the mechanisms responsible for the relaxation of charge carriers in
semiconductor systems is crucial for the development of novel devices based on these
materials. Transient four-wave mixing (FWM) is a ...
