Comprehensive measurements, including transfer curve, temperature stress (TS), negative bias temperature stress (NBTS), activation energy, and density of states (DOS), were conducted to assess the electrical properties of the TFTs. The results indicated that higher oxygen concentrations during ...
In the derivation leading to Eq. (1.102), only one quantum state ne = 1 was considered. Once E > Ee,z(2), as an example, an electron of a given total energy Ee can be found in either ne = 1 or ne = 2 state so that the density of states doubles. The total density of states...
An analytical electron density of states (DOS) for zigzag and armchair single-wall carbon nanotubes (CNTs) are derived in this paper. The derivation originates from the tight-binding energy dispersion relation for CNTs and reveals the essential physics such as periodic van-Hove singularities and it...

The experimental investigation of the density of states of liquids at low energies is much less explored due to the fact that many techniques used to study liquid properties, such as infrared, Raman and nonlinear IR, do not have sufficient energy resolution to probe the details at very low ene...
Electrons in the higher-energy states [the energies above μ(T1) in Fig. 3] can transition to the available lower-energy states by giving up this excess energy to the lattice, resulting in a heat flux, JQ. As an externally applied electric field accelerates charged carriers, they do not ...
The simplest example is associated with the microcanonical ensemble whose density of states is written as\(\rho (p)=\delta (p-1/W)\). This form enables us to analitically express all forms of generalized entropies as $$\begin{aligned} S_g=W\int \limits _0^1 \delta \left( p-\frac...

Oscillations in the probability density of quantum transitions of the eigenstates of a chaotic Hamiltonian within classically narrow energy ranges have been shown to depend on closed compound orbits. These are formed by a pair of orbit segments, one in the energy shell of the original Hamiltonian ...
of radiuskD, the Debye wavevector. The first assumption is notably violated in liquids in which the late-time (low energy) dynamics is dominated by diffusion5, which induces a constant contribution to the density of states observed both in molecular dynamics simulations and in experiments. ...
