Web16 okt. 2010 · The minimum metallic conductivities and mobilities, the critical concentrations of main impurities and majority charge carriers, and the compensation coefficients of the n-GaAs, p-Ge, and p-CdSnAs2〈Cu〉 compounds have been presented. It has been shown that experimental data agree with the concept of mobility threshold. Web1 apr. 1982 · A high location of the crucible (crystals 40 and 254 G. Jacob ci al. / Dislocations in GaAs 41 in table 1) leads to a difficult control of the shape of the neck, so that only 4 mm diameter necks have been obtained, with sometimes occur- rence of twins (fig. 9). The difficulty in the diame- ter control of the neck and the occurrence of twins is ...
Web6 nov. 2012 · GaN based epitaxial films form active layers in UV-blue-green light emitting diodes, laser diodes and high power electronic devices. Traditionally, transmission electron microscopy, X-ray diffraction, cathodoluminescence and wet etching based techniques are used to measure dislocation density and film quality. http://www.ioffe.ru/SVA/NSM/Semicond/AlGaAs/index.html
Web14 okt. 2024 · Crack-free AlN films with threading dislocation density (TDD) below 10 9 cm −2 are needed for deep-UV optoelectronics. This is typically achieved using pulsed lateral overgrowth or very thick buffer layers (>10 μm), a costly and time-consuming approach.A method for conventional metalorganic chemical vapor deposition growth of AlN/SiC films …
