STR has published a new paper: “Critical aspects of AlGaInP-based LED design and operation revealed by full electrical-thermal-optical simulations” by Olga Fedorova, Kirill Bulashevich, and Segrey Karpov. It is available as an open access publication. All results were obtained using SimuLED software: SiLENSe for bandgap engineering, SpeCLED for simulation of current spreading and self heating, RATRO for light extraction.
