Blochoszillationen in GaAs/AlGaAs Übergittern nach Anregung deutlich oberhalb der Bandlücke
Abstract
Bloch oscillations of wave packets in semiconductor superlattices are observed by THz-emission spectroscopy after pulsed photo-excitation well above the fundamental band-gap. We show that Bloch oscillations are induced by excitation of states in both the first and the second electron miniband
