Defect Properties and Band Energetics of Atomic Layer Deposited MoOX on Crystalline Si

open access: yesAdvanced Materials Interfaces
Molybdenum oxide (MoOx) thin films have been extensively investigated for selective hole extraction in solar cells, including as an efficient alternative to the well‐studied p‐type a‐Si:H layers in Si heterojunction cells.

Density of states in spectral geometry

open access: yesCommentarii Mathematici Helvetici, 1993
It is well known that the concept of integrated density of states was introduced by physicists in quantum theory of solids. In the paper under review a geometrical formalization of this notion is proposed and for the particular case of the manifolds with compact quotient some necessary and sufficient conditions for its existence are pointed out.

Investigation on nickel ferrite nanowire device exhibiting negative differential resistance — a first-principles investigation

open access: yesCondensed Matter Physics, 2017
The electronic property of NiFe_2O_4 nanowire device is investigated through nonequilibrium Green’s functions (NEGF) in combination with density functional theory (DFT).

Entropy Densities for Algebraic States

open access: yesJournal of Functional Analysis, 1994
Algebraic (or finitely correlated) states are translation-invariant states on an infinite tensor product \(C^*\)-algebra, whose construction is rather general, including quantum Markov chains. For a strongly mixing algebraic state, the authors obtain the relation between the mean entropy and another entropy density, which means the macroscopic ...

Polaron density of states of AlAs/GaAs/AlAs and PbS/PbTe/PbS type quantum well

open access: yesCondensed Matter Physics, 2007
Polaron energy spectrum of AlAs/GaAs/AlAs and PbS/PbTe/PbS quasi two-dimensional heterostructure as a function of the wave-vector is investigated based on the adiabatic approximation and the Ritz variational technique.

Peeling off the surface: Pt‐decoration of WSe2 nanoflakes results in exceptional photoelectrochemical HER activity

open access: yesSusMat, 2022
Photoelectrochemical (PEC) hydrogen evolution reaction (HER) was studied on exfoliated, pristine and Pt‐decorated tungsten diselenide (p‐WSe2) nanoflake samples, using a previously developed microdroplet PEC microscopy approach.

Loschmidt echo and the local density of states [PDF]

open access: yesPhysical Review E, 2009
Loschmidt echo (LE) is a measure of reversibility and sensitivity to perturbations of quantum evolutions. For weak perturbations its decay rate is given by the width of the local density of states (LDOS). When the perturbation is strong enough, it has been shown in chaotic systems that its decay is dictated by the classical Lyapunov exponent.
