Paper Abstract

Two geometries are essential in the Magnetophonon Resonance (MPR) experiments in the layered semiconductor structures. First, the magnetic field and current are perpendicular to layers--MPR in vertical transport. Second, magnetic field is perpendicular to layers, whereas current occurs in layers-- MPR in parallel transport in superlattices and Multiple- Quantum-Well-Structures (MQWS). This anisotropy is connected mainly with anisotropy of the electron effective mass. Simultaneously, other important deferences are placed in the electron transport in superlattices and MQWS for these main directions. The peculiarities caused by motion in minibands (vertical transport) and influence of the thermal stress (parallel transport) as well as contribution of the confident phonons was discussed. The present paper discusses the MPR works in the superlattices and MQWS which were conducted during the last decade.
