Dislocation-assisted electron and hole transport in GaN epitaxial layers
Fabrication of TSD- and TED-dominant GaN Epitaxy
To introduce distinct dislocation configurations, two GaN epitaxial structures were grown on sapphire substrates via metal-organic chemical vapor deposition (MOCVD). For TSD-dominant samples, a…

Adiabatons in a double tripod coherent atom-light coupling scheme
Initial equations
Now, we investigate a DT type atomic system (Fig. 1b) involving three metastable ground states \(|0\rangle\), \(|1\rangle\) and \(|2\rangle\), as well as excited states \(|e_{1}\rangle\) and \(|e_{2}\rangle\). Six laser fields…

Non-collinear magnetism and topological electronic structure in the half-Heusler compounds PrNiBi and PrPtBi
The half-Heusler XYZ compound exhibits a non-centrosymmetric cubic structure, crystallizing in the cubic C1b crystal structure with the F\(\:\stackrel{-}{4}\)3m space group, where X and Y are transition metal or rare earth elements, while Z is a…

A crack detection and quantification method using matched filter and photograph reconstruction
UAV imagery and crack characteristics
Based on their morphology and propagation trends, cracks in bridge pavements can be classified into four types: transverse, longitudinal, block, and grid cracks. The two types share several common…

Gravitational catalysis of nuclear synthesis from positrons, electrons and neutrinos
The question thus arises on how nature could build from these five particles (e+, e−, ν1, ν2, ν3) the incredibly complex and fascinating environment in which we live. In particular it is difficult to understand how these five particles have…
