Dependencies of the peak position on the bias voltage. Dependences of the peak position of the THz emission line and the emission line width
on the bias voltage. The solid line corresponds to a linear fit of the experimental
emission maximum (Emax) versus bias voltage (V ) with a gradient of ≈32 μeV/V. The dashed line is a guide for the eye.
