Quasiballistic correction to the density of states in three-dimensional metal
, 1999 We study the exchange correction to the density of states in the three-dimensional metal near the Fermi energy. In the ballistic limit, when the distance to the Fermi level exceeds the inverse transport relaxation time $1/\tau$, we find the correction ...

Fermi-level pinning and charge neutrality level in germanium
Applied Physics Letters, 2006 The Schottky barrier height in metal/Ge contacts shows weak dependence on the metal work function indicating strong Fermi-level pinning close to the Bardeen limit. The pinning factor S is about 0.05 and the charge neutrality level (CNL) is only about 0.09eV above the top of the valence band.

Coulomb Drag Between Parallel Ballistic Quantum Wires
, 1999 The Coulomb drag between parallel, {\it ballistic} quantum wires is studied theoretically in the presence of a perpendicular magnetic field B. The transresistance R_D shows peaks as a function of the Fermi level and splitting energy between the 1D ...

Role of the van Hove Singularity in the Quantum Criticality of the Hubbard Model [PDF]
, 2011 A quantum critical point (QCP), separating the non-Fermi liquid region from the Fermi liquid, exists in the phase diagram of the 2D Hubbard model [Vidhyadhiraja et. al, Phys. Rev. Lett. 102, 206407 (2009)].

Study of adsorption states in ZnO–Ag gas-sensitive ceramics using the ECTV curves method
Технологія та конструювання в електронній апаратурі, 2013 The ZnO–Ag ceramic system as the material for semiconductor sensors of ethanol vapors was proposed quite a long time ago. The main goal of this work was to study surface electron states of this system and their relation with the electric properties of ...

Magnetotransport of dirty-limit van Hove singularity quasiparticles
Communications Physics, 2021 Strongly correlated materials can exhibit deviations from Fermi-liquid behavior partly due to anomalies in the density of states at the Fermi level, such as van Hove singularities.
