Impact of surface charge depletion on the free electron nonlinear response of heavily doped semiconductors
arXiv:2205.03123 · doi:10.1103/PhysRevLett.129.123902
Abstract
We propose surface modulation of the equilibrium charge density as a technique to control and enhance, via an external static potential, the free electron nonlinear response of heavily doped semiconductors. Within a hydrodynamic perturbative approach, we predict a two order of magnitude boost of free electron third-harmonic generation.
