The Efros–Shklovskii (ES) Coulomb gap in the one-electron density of localized states and
the ES law of the variable range hop** conductivity were coined 50 years ago. The theory …

Two recent electronic transport experiments from Columbia University and Harvard
University have reported record high mobility and low channel densities in flux-grown …

In this study, we report the structural, hardness, optical, and high temperature thermoelectric
properties of Gd-doped lanthanum cobaltite La 1− x Gd x CoO 3 (x= 0.0, 0.2, 0.4, 0.6). The …

Photoconductivity of novel materials is the key property of interest for design of
photodetectors, optical modulators, and switches. Despite the photoconductivity of most …

The measurements of anisotropic magnetoresistance (AMR), planar Hall effect (PHE) and
temperature-dependent conductivity in materials with strong spin-orbit coupling yield …

We present and generalize the preparation conditions and properties of strongly
compensated Ge films grown on semi-insulating GaAs (100) substrates by vacuum …

Oxides with low O 2− lattice diffusion rate are critical for the development of topcoat
materials for next generation thermal barrier coatings (TBCs) working at> 1600° C to prevent …

We are honored to dedicate this article to Emmanuel Rashba on the occasion of his 95
birthday. In the ideal disorder-free situation, a two-dimensional bandgap insulator has an …

We show a transition from a bound state to a continuum resonance in a shallow quantum
well (QW) by electrostatic gating to bend the conduction band edge. This bound state …

We present electrical properties of heavily doped and completely compensated Ge films
grown on semiinsulating GaAs (100) substrates by vacuum evaporation. The thin (∼ 100 …
