Abstract

Using our novel high field terahertz source we performed various nonlinear experiments on semiconductor nanostructures. In one-dimensional nonlinear propagation experiments on n-type GaAs we observed ballistic high-field transport and THz-induced interband tunneling of electrons. Two-dimensional THz correlation spectroscopy performed on intersubband transitions of two coupled quantum wells shows distinct polaronic features of the intersubband transitions.
