Most optoelectronic devices operate at high photocarrier densities, where all semiconductors suffer from enhanced nonradiative recombination. Nonradiative processes proportionately reduce photoluminescence (PL) quantum yield (QY), a performance metric that directly dictates the maximum device efficiency. Although transition-metal dichalcogenide (TMDC) monolayers exhibit near-unity PL QY low exc...

The purpose of this study is to analyze the influence resistance change and adaptability on management at Vocational High School (VHS) in West Java, Indonesia. Using survey quantitative approach, research was conducted 61 VHS 27 regencies/cities with a representative sample 183 teachers. data were analyzed by descriptive Partial Least Square (PLS). It found that has negative management, positiv...

—————————————————— Combining the results of tunneling, photoemission and thermodynamic studies, the pseudogap is unambiguously demonstrated to be caused by Van Hove nesting: a splitting of the density of states peak at (π, 0). The fact that the splitting remains symmetric about the Fermi level over an extended doping range indicates that the Van Hove singularity is pinned to the Fermi level. De...

A new approach to DSMC collision modelling, called viscosity-DSMC or μ-DSMC, is described in which the time-averaged temperature is used to set the characteristic collision cross-section in each cell such that the Chapman-Enskog viscosity is that given by any desired viscosity law μ = μ (T ), including a curve fit to experimental data. For example, a hard sphere collision model, with hard spher...

Recently, moiré superlattices have been found on the surface of topological insulators due to rotational misalignment topmost layers. In this work, we study effects states using a continuum model Dirac electrons moving in periodic potential. Unlike twisted bilayer graphene, cannot host isolated bands their nature. Instead, find (high-order) van Hove singularities (VHS) band structure that give ...

This paper examines the welfare effects of market segmentation using the example of the video rental and sales markets (both VHS and DVD formats). I consider a market with two types of buyers: institutional and individual buyers. Institutional buyers rent the good to low-value individuals, while relatively high-value individuals purchase the good directly rather than renting it. Copyright law i...

Dilated cardiomyopathy is a relatively common disease in pet rats (Rattus norvegicus); however, there lack of radiographic references for the normal cardiac size this species. The aim prospective, anatomical and reference interval study was to establish quantitative range measurements vertebral heart score (VHS) rats. Right lateral (RL), ventrodorsal (VD), dorsoventral (DV) radiographs clinical...

We describe the finding of a novel viral haemorrhagic septicaemia virus (VHSV) Genotype III strain that caused disease of both a neurological and septicaemic nature in seawater-farmed rainbow trout Oncorhynchus mykiss in Storfjorden, Norway. In November 2007, an outbreak of VHS associated with slightly elevated mortality was confirmed at a seawater site rearing rainbow trout (90 to 440 g). With...

This research aims to determine work willingness after industrial placement of XII-grade students in the study program electrical power installation engineering (TITL) at VHS 5 Padang. The method uses a quantitative descriptive approach using similarity terms cognitive, affective, and psychomotor. results this indicate will 31 is likely be more interested entering higher education or entreprene...
