PhD positions funded by the GACR Project: Controllable GHz-THz Nonlinear Optics in Semiconductor Superlattices

Transient and steady state nonlinearities in semiconductor materials are well understood in the visible and near infrared ranges. In contrast, little is known about the nonlinear response in gigahertz (GHz) and terahertz (THz) spectral ranges, and materials with strong nonlinear terahertz response are difficult to find. Semiconductor superlattices (SSLs) are the ideal system to study nonlinear transport and optics and controllable GHz-THz nonlinearities in SSLs [1,2]. The PhD students will be involved in analytical and numerical studies and the method combines bandstructure engineering, Nonequilibrium Green’s Functions and the Boltzmann Equation. The theory will be developed in parallel with an experimental effort.

The PhD students will develop the research at the Academy of Sciences and will receive their PhD as regular students at Charles University.
