Localization landscape theory of disorder in semiconductors. III. Application to carrier transport and recombination in light emitting diodes
Chi-Kang Li, Marco Piccardo, Li-Shuo Lu +7
This paper introduces a novel method to account for quantum disorder effects into the classical drift-diffusion model of semiconductor transport through the localization landscape…
Localization landscape theory of disorder in semiconductors II: Urbach tails of disordered quantum well layers
Marco Piccardo, Chi-Kang Li, Yuh-Renn Wu +7
Urbach tails in semiconductors are often associated to effects of compositional disorder. The Urbach tail observed in InGaN alloy quantum wells of solar cells and LEDs by biased ph…
Localization landscape theory of disorder in semiconductors I: Theory and modeling
Marcel Filoche, Marco Piccardo, Yuh-Renn Wu +3
We present here a model of carrier distribution and transport in semiconductor alloys accounting for quantum localization effects in disordered materials. This model is based on th…
Direct Measurement of Auger Electrons Emitted from a Semiconductor Light-Emitting Diode under Electrical Injection: Identification of the Dominant Mechanism for Efficiency Droop
Justin Iveland, Lucio Martinelli, Jacques Peretti +2
We report on the unambiguous detection of Auger electrons by electron emission spectroscopy from a cesiated InGaN/GaN light emitting diode (LED) under electrical injection. Electro…
