Structural properties, interface modes and magnetophonon resonances in the double quantum well structure.

The Double Quantum Well structure (DQWs) of special engineering providing a rectangular shape of QW's, is investigated. The Scanning Transmission Electron Microscopy (STEM) observations confirmed a high quality of interfaces and smooth change of the In-content in a rectangular shape QW. Micro-Raman experiment enabled to detect interface phonons in DQWs which are manifested in Magnetophonon Resonance. This contribution of interface phonons in the electron magneto-transport is important because as could be expected, the role of these phonons will increase in case of electron transport in the Double Quantum Wires fabricated from DQWs investigated.
