Recent advances in materials fabrication have enabled the manufacturing of ordered 2D
electron systems, such as heterogeneous interfaces, atomic layers grown by molecular …

Granular metals are arrays of metallic particles of a size ranging usually from a few to
hundreds of nanometers embedded into an insulating matrix. Metallic granules are often …

Superconductor-insulator transitions, especially in thin films, can provide the simplest
examples of the continuous quantum phase transition paradigm. Quantum phase transitions …

The conventional theory of metals is in crisis. In the past 15 years, there has been an
unexpected sprouting of metallic states in low-dimensional systems, directly contradicting …

We present the results of an experimental study of the current-voltage characteristics in a
strong magnetic field (B) of disordered, superconducting, thin films of amorphous indium …

The study of thin superconducting films has been an important component of the science of
superconductivity for more than six decades. It played a major role in the development of …

We extend our previous discussion of the Bose metal to the field-tuned case. We point out
that the recent observation of the metallic state as an intermediate phase between the …

Abstract Two-dimensional (2D) crystals are attracting growing interest in condensed matter
physics, since these systems exhibit not only rich electronic and photonic properties but also …

Optical properties of ultrathin layers (<? format?>< 50 Å) of Au and Pb quench condensed
on amorphous germanium (α-G e) have been measured in situ at 10 K. The development of …

A theory of the zero-temperature superconductormetal transition is developed for an array of
superconductive islands (of size d) coupled via a disordered two-dimensional conductor …
