In this work, a deliberate etching-based top-down approach is proposed to fabricate the GaN nanorod (NR) Schottky barrier diode (SBD). As key step during fabrication, impact of wet-etching process on device performance systematically studied. By virtue reduced surface states at sidewall, NR SBD with substantially improved, delivering forward turn-on voltage 0.65 V, current density ∼10 kA/cm2 3 ...

The present research proposes a methodology to improve the estimation of unknown parameters unitary diode model photovoltaic panel. To check accuracy, comparison with other methodologies known in scientific literature is made. Through an iterative process, best value series resistance and ideality factor for different temperature irradiance conditions are identified. objective determine simplif...

Memristors have pinched hysteresis loops in the V − I plane. Ideal memristors are everywhere non-linear, cross at zero and are rotationally symmetric. In this paper we extend memristor theory to produce different types of non-ideality and find that: including a background current (such as an ionic current) moves the crossing point away from zero; including a degradation resistance (that increas...

The Coach6 software and the CoachLabII+ measuring console coupled with a computer equipped appropriate voltage current sensors were used to determine current-voltage power-voltage characteristics of photovoltaic cells. for single cell cells connected in series parallel tested depending on light intensity. Using simplified theoretical model based one-diode equivalent circuit Shockley diode equat...

Calculations of the absorptive partitioning of secondary organic aerosol components were carried out using a number of methods to estimate vapour pressure and nonideality. The sensitivity of predicted condensed component masses, volatility, O:C ratio, molar mass and functionality distribution to the choice of estimation methods was investigated in mixtures of around 2700 compounds generated by ...

The effects of thermodynamic non-ideality on the forms of sedimentation equilibrium distributions for several isoelectric proteins have been analysed on the statistical-mechanical basis of excluded volume to obtain an estimate of the extent of protein solvation. Values of the effective solvation parameter delta are reported for ellipsoidal as well as spherical models of the proteins, taken to b...

In this study the microstructure of alcohol binary mixtures (toluene and cyclohexane) is investigated from molecular dynamics simulations. case cyclohexane mixtures, we show that strong deviation ideality result formation nanophases molecules gathered in aggregates hydrogen bonds leading to spatial heterogeneity. Nanophases disappear as alkyl chain size increases because hydrophobic interaction...

We examine the Galilean invariance of standard lattice Boltzmann methods for two-phase fluids. We show that the known Galilean invariant term that is cubic in the velocities, and is usually neglected, is the main source of Galilean invariance violations. We show that incorporating a correction term can improve the Galilean invariance of the method by up to an order of magnitude. Surprisingly in...
