WPI Novel Semiconductor Nanocomposite Material Response to Light
2016/11/4
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used in a variety of applications, including mi...
Modeling ablative behavior and thermal response of carbon/carbon composites
Chemical ablation Carbon carbon composites Altitude effect Oxidation protection
2015/3/24
Carbon/carbon composites usually work in complex thermo-chemical environments, surface recession is thus inevitable due to chemical ablation and further affects the system stability and safety. In thi...
Self-phase modulation of a single-cycle terahertz pulse by nonlinear free-carrier response in a semiconductor
Self-phase modulation single-cycle terahertz pulse nonlinear free-carrier response semiconductor
2012/2/24
We demonstrate the self-phase modulation (SPM) of a single-cycle THz pulse in a semiconductor, using bulk n-GaAs as a model system. The SPM arises from the heating of free electrons in the electric fi...
