Anomalous terahertz photoconductivity caused by the superballistic flow of hydrodynamic electrons in graphene
M. Kravtsov, A. L. Shilov, Y. Yang +18
Light incident upon materials can induce changes in their electrical conductivity, a phenomenon referred to as photoresistance. In semiconductors, the photoresistance is negative,…
