Interband impact ionization and nonlinear absorption of terahertz radiations in semiconductor heterostructures
J. C. Cao
We have theoretically investigated nonlinear free-carrier absorption of terahertz radiation in InAs/AlSb heterojunctions. By considering multiple photon process and conduction-vale…
