Schmitt-Rink, "Generation of Ultrashort Electrical Pulses through Screening by
Virtual Populations in Biased Quantum Wells" Phys. Rev. Lett. 59, 1018-1021,
(1987). The authors consider theoretically a semiconductor quantum well subject
to an electrostatic field normal to the layer and a strong monochromatic laser field in
the transparency region below the absorption edge. They shown that ultrashort optical
pulses generate ultrashort voltage pulses because the virtual electron-hole population
induced by the laser field partially screens the applied static field. They predict that
voltages >1 V could be generated in micron-thick multiple-quantum-well structures by
use of low-power short-pulse lasers
