Optimization of passivation in AlGaN/GaN heterostructure microwave transistor fabrication by ICP CVD [PDF]
Modern Electronic Materials, 2020 We have studied the effect of silicon nitride (SiN) dielectric passivating film deposition by inductively coupled plasma chemical vapor deposition (ICP CVD) on the parameters of AlGaN/GaN heterostructure high electron mobility transistors (HEMT).

Control of yellow photoluminescence in AlGaN/GaN heterostructures [PDF]
Modern Electronic Materials, 2019 Photoluminescence with the peak corresponding to yellow color of the visible spectrum (so-called yellow luminescence) originates from deep levels in the GaN buffer layers of heterostructures and depends on heterostructure growth conditions.

Theoretical Study of Gamma-ray Pulsars [PDF]
Journal of Astronomy and Space Sciences, 2016 We use the non-stationary three dimensional two-layer outer gap model to explain gamma-ray emissions from a pulsar magnetosphere. We found out that for some pulsars like the Geminga pulsar, it was hard to explain emissions above a level of around 1 GeV.
