CREATION OF A DYNAMIC QUANTUM SUPERLATTICE IN A 2-DIMENSIONAL ELECTRON-SYSTEM IN A SEMICONDUCTOR BY MEANS OF AN INTENSE PIEZOELECTRIC FIELD

A new method is proposed for the creation of a dynamic quantum superla ttice in a two-dimensional electronic system in a semiconductor crysta l at low temperatures. This method is based on the action of an intens e piezoelectric field, produced by a standing transverse hypersonic wa ve, on a two-dimensional electron system placed near the crystal sampl e surface. The standing hypersonic wave is excited under the action of a microwave field in a prismatic beam resonator made from a dielectri c crystal with strong piezoelectric coupling.
