In this work, we perform numerical simulations of a conventional GaN LED chip within the framework of the combined electrical/thermal/light approach. A GaN LED chip grown on a sapphire substrate is investigated. We calculate the dependencies of the forward voltage, light output power, wall‐plug efficiency, and uniformity of current spreading on the variations in the electrode geometry. Modelling is...
In this report, we study, by means of numerical simulation, the impact of the active layer properties and device geometry on the performance of the “solar blind” UV MSM detector based on AlGaN and BGaN alloys. The parameters investigated, using the Silvaco Athena and Atlas tools, were: (i) the Schottky contact width and thickness; (ii) the ternary (AlGaN or BGaN) physical properties, including the...
