A study of the zero magnetic field metal-insulator transition in SiGe quantum well structures and its associated phase diagram reveals the occurrence of two quantum phase transitions in the insulating regime as a function of temperature and carrier density. This is observed as a rapid fall of the re

We investigate Landau level formation in closely coupled double quantum wells by measuring the longitudinal resistance (R ) as a function of both perpendicular (B , ) and in-plane (B , ) magnetic fields. B , distorts the dispersion curve resulting in a continuously tunable, non-parabolic, two-compon
Landau-level lifetimes are determined from saturation cyclotron resonance (CR) in wide parabolic wells, quantum wells and bulk PbTe-Pb \V Eu V Te systems. These narrow gap structures exhibit strong band non-parabolicity necessary to terminate the normally equi-spaced Landau-level ladder. It was not
