TL;DR: In this article , the effects of off-angled sapphire substrates on the surface morphology and crystal quality of β-Ga2O3 films have been systematically investigated, and the results indicate that to some extent the larger off-angle substrate could lead to the smoother surface morphology, which may result in a higher crystal quality.

TL;DR: In this article, the segregation and desorption of Ge atoms in Si1−x Ge x films were investigated by dual-source jet-type inductively coupled plasma chemical vapor deposition (ICPCVD).

TL;DR: In this paper , the robustness of AlGaN/GaN Schottky barrier diodes (SBDs) was demonstrated for inductive transient shocks in power switching applications.

TL;DR: In this paper, the authors developed an LED thermal resistance and thermal interface material evaluation method using LEDs with an internal sensor unit by both steady-state and transient thermal measurements, which used low-cost equipment, while realizing improved accuracy.

TL;DR: In this article, the temperature-dependent stress state in the barrier layer of AlGaN/GaN heterostructures grown on sapphire substrate was investigated by ultraviolet (UV) near-resonant Raman scattering.
