Mesoscopic physics refers to the physics of structures larger than a nanometer (one billionth
of a meter) but smaller than a micrometer (one millionth of a meter). This size range is the …

Experimental results on metal–insulator transitions and the anomalous properties of strongly
interacting two-dimensional electron systems are reviewed and critically analyzed. Special …

We have systematically studied the electron transport in the vicinity of the transitions from the
ν= 1 and 1/3 quantum Hall liquids to the Hall insulator, in a wide variety of samples. Our …

We discuss the effect of dissipation on quantum phase transitions. In particular, we
concentrate on the superconductor to insulator and quantum Hall to insulator transitions. By …

A study of the temperature evolution of the recently discovered reflection symmetry of the
diagonal resistivity, ϱxx, near quantum Hall-to-insulator transitions, is presented. The data is …

The general theoretical definition of an insulator is a material in which the conductivity
vanishes at the absolute zero of temperature. In classical insulators, such as materials with a …

We present a magnetotransport study of a disordered two-dimensional hole system in a
strained Ge quantum well. As the magnetic field is increased, a clear transition from a low …

The magnetotransport in single layer graphene has been experimentally investigated in
magnetic fields up to 18 T as a function of temperature. A pronounced T dependence is …

We present an experimental study of the fate of the delocalized states as B→ 0 in a
disordered two-dimensional electron gas system. Evolving peaks in the longitudinal …

We report quantum Hall experiments on the plateau-insulator transition in a low mobility In
0.53 Ga 0.47 As/InP heterostructure. The data for the longitudinal resistance ρ xx follow an …
