The molecular geometry of the complex of gallium trichloride with ammonia, Cl 3Ga.NH 3, has been studied by electron diffraction. The most important internuclear distances in terms of r a parameters are as follows: r(Ga-Cl) = 2.142±0.005, r(Ga-N) = 2.057±0.011, r(ClCl) = 3.642±...
Bi doping shortens excited-state lifetimes due to formation of DY−charge recombination centers. Using nonadiabatic molecular dynamics and time-domain density functional theory, we demonstrate that the DY−center forms
Full size image Previous studies on [NH3(CH2)nNH3]MCl4(n = 2, 3, 4, 5, and 6;M = Mn, Co, Cu, Zn, and Cd) single crystals have been reported as follows: the research related to [NH3(CH2)nNH3]MnCl4withnvalues of 2, 3, 4, and 5, andM = Mn, was discussed...
Hermes et al.17 proposed a third model based on polycrystalline thin film data with (110)t domain boundaries. The determination of twin geometry from single-crystal electron diffraction patterns can be made by direct inspection and does not require numerical refinement of test models. Furthermore,...
Moreover, p-GaN layers are used to create photocathode with negative electron affinity [1] and normally-off transistors [2]. One of the main difficulties in III-nitride technology is obtaining of high-quality layers with the p-type conductivity and high concentration of charge carriers. The ...
2.1. Computational domain 2.2. Governing equations RANS method is used to solve the mass, momentum, energy,and species transport equations in compressible fluids. The governing equations are given as: (1) Mass conservation: The physical model of the premixed swirling combustor performed in the prese...
