6H-SiC samples were examined by ESR technique in temperature range from 5 K up to 300 K. Two kinds of ESR lines were observed: a single line at g = 2.0054 ± 0.0007, called X-line, and a triplet corresponding to isolated nitrogen defect. Ionization e

Far infrared magnetooptical investigations of shallow donors in epitaxial MOCVD GaN layers show two types of shallow donors. In relaxed layers, a donor with an ionization energy of 35 meV was found. In strained, undoped and Si doped samples, a donor

Growth of GaN/Al2O3 layers by MOVPE has been investigated. Precise optimization of the growth parameters results in films with extremely high electron mobility: 900 cm2/Vs at 300K and 4000 cm2/Vs at 77K. The influence of the growth parameters on film
