Main Results of Scientific Work
The methodology for the analysis of relaxation capacity curves after Schottky diode voltage changing was proposed. The methodology deals with analyzing the curve as the dependence of the capacity derivative on the time logarithm. With such analysis, each monoexponential curve contributing to the relaxation curve is represented as a separate peak and may be isolated with a significant accuracy.
The main results and applications are describes in the following article: Polyakov A.Y., et al. Current relaxation analysis in AlGaN/GaN high electron mobility transistors, Journal of Vacuum Science and Technology B: Nanotechnology and Microelectronics. v.35, i.1, 2017. p.011207-(1-10).
