For about 20 years, it has been the prevailing view that there can be no metallic state or
metal-insulator transition in two dimensions in zero magnetic field. In the last several years …

Among very-low-disorder systems of condensed matter, the high-mobility two-dimensional
electron gas (2DEG) confined in aluminum gallium arsenide (AlGaAs)–gallium arsenide …

In quasi two-dimensional electron and hole systems spin-orbit (SO) coupling strongly
influences both the orbital and spin components of motion. In inversion asymmetric systems …

The interplay between strong Coulomb interactions and randomness has been a long-
standing problem in condensed matter physics. According to the scaling theory of …

In this review, the classification of magnetoresistance effects, the electrical conduction
mechanisms without and with magnetic field, and the spintronics are briefly summarized …

We present an in-depth study of the spin-orbit (SO) interactions occurring in inversion-
asymmetric two-dimensional hole gases at semiconductor heterointerfaces. We focus on …

We investigate spin transport of heavy holes in III-V semiconductor quantum wells in the
presence of spin-orbit coupling of the Rashba type due to structure-inversion asymmetry …

Coupling the spin degree of freedom to the anisotropic orbital motion of two-dimensional
(2D) hole systems gives rise to a highly anisotropic Zeeman splitting with respect to different …

This paper reviews the spin orientation of spin-3/2 holes in quantum wells. We discuss the
Zeeman and Rashba spin splitting in hole systems that are qualitatively different from their …

We have studied the Zeeman splitting in ballistic hole quantum wires formed in a (311) A
quantum well by surface gate confinement. Transport measurements clearly show lifting of …
