Hot electron diffusion, microwave noise, and piezoresistivity in Si from first principles

Posted by dbos Caltech

Kavli Affiliate: Austin J. Minnich | First 5 Authors: Benjamin Hatanpää, Austin J. Minnich, , , | Summary: Ab-initio calculations of charge transport properties in materials without adjustable parameters have provided microscopic insights into electron-phonon interactions which govern charge transport properties. Other transport properties such as the diffusion coefficient provide additional microscopic information and are […]

Probing nontensorial gravitational waves with a next-generation ground-based detector network

Posted by dbos Peking

Kavli Affiliate: Lijing Shao | First 5 Authors: Jierui Hu, Dicong Liang, Lijing Shao, , | Summary: In General Relativity, there are only two polarizations for gravitational waves. However, up to six polarizations are possible in a generic metric theory of gravity. Therefore, measuring the polarization content of gravitational waves provides an efficient way to […]
