This paper analyses the influence of the GaN and Si3N4 passivation (or "cap") layer on the top of the AlGaN barrier layer on the performance and reliability of Schottky barrier diodes with a gated edge termination (GET-SBDs). Both GaN cap and Si3N4 cap devices show similar dc characteristics but a higher density of traps at the SiO2/GaN interface o...
The universality of a key recovery mechanism: triple junction migration in high strain nanostructures is revealed herein. This migration is the only means to uniformly coarsen deformed lamellar microstructures. Migration of medium to high angle geometrically necessary boundaries at triple junctions is resisted by strong pinning phenomena. Pinning b...

The present study reports the systematic study on the effect of film thickness on the optical and electrical properties of transparent tetragonal (α) WO3 phase, synthesized using pulsed laser deposition. The WO3 films of various thicknesses 250 ± 4 (S1), 350 ± 2 (S2), 750 ± 5 (S3) and 1150 ± 4 (S4) nm were obtained by varying the deposition time 8,...

We have investigated the ionic conductivity and dielectric relaxation in Li2B4O7 (LBO) and Li2OB2O3-Ta2O5 (LBTO) glasses. The sample was synthesized by using the melt quenching method. The frequency dependence of the electrical data from the LBO and LBTO glasses has been analyzed in the frameworks of the impedance Cole-Cole formalism and the univer...

An open air stockpile of conical shape was formed with 3.5 m base diameter and 5 m height using 500 tons of − 200 mm size ROM thermal coal on a concrete floor. Coal sample from the stockpile were collected at 30 days interval for analysis of various chemical properties like; proximate analysis, ultimate analysis, gross calorific value (GCV) and var...

The present paper deals with the flow of Cross rheological fluid along a stationary rigid plate caused by stream-wise pressure gradient. Flow field is affected by uniform magnetic field acting normal to the plate axis. Interaction of flow field with chemically reacting solute is modeled through the advection–diffusion equation in which temperature ...

To investigate the influence of adding CeO2 on the hydrogen storage characteristics of Sm–Mg–Ni-based SmMg11Ni-type alloy, mechanical milling was utilized to synthesize SmMg11Ni and SmMg11Ni + 5 wt.% CeO2 (named SmMg11Ni–5CeO2) alloys. The microstructure of as-cast and as-milled samples was measured via X-ray diffractometer and transmission electro...

Ballistic properties of cast double-base propellants can be affected by the thermal treatment of the propellant grain before firing. In this work, we study the effect of initial grain temperature on both burning rate and activation energy of the double-base propellant. The burning rate of cast double-base propellant has been reported for different ...
