D. S. Chemla, D. A. B. Miller, and S. 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
