Patent number: 10134927Abstract: A photoconductive switch consisting of an optically actuated photoconductive material, e.g. a wide bandgap semiconductor such as SiC, situated between opposing electrodes. The electrodes are created using various methods in order to maximize reliability by reducing resistive heating, current concentrations and filamentation, and heating and ablation due to the light source. This is primarily accomplished by the configuration of the electrical contact geometry, choice of contacts metals, annealing, ion implantation, creation of recesses within the SiC, and the use of coatings to act as encapsulants and anti-reflective layers.Type: GrantFiled: July 8, 2016Date of Patent: November 20, 2018Assignee: Lawrence Livermore National Security, LLCInventors: Lars Voss, Mihail Bora, George Caporaso, Adam Conway, Hoang T.
