Direct measurement of Auger electrons emitted from a semiconductor light-emitting diode under electrical injection: identification of the dominant mechanism for efficiency droop.

TL;DR: The droop phenomenon in GaN light-emitting diodes originates from the excitation of Auger processes, which shows that hot carriers are being generated in the active region (InGaN quantum wells) by an Auger process.
Journal ArticleDOI

Suppressing quantum errors by scaling a surface code logical qubit

Rajeev Acharya, +157 more

TL;DR: In this article , the authors report the measurement of logical qubit performance scaling across several code sizes, and demonstrate that their system of superconducting qubits has sufficient performance to overcome the additional errors from increasing qubit number.
Journal ArticleDOI

The efficiency challenge of nitride light-emitting diodes for lighting

TL;DR: It is shown that both from the point of view of cost of ownership and carbon emissions reduction, the relevant metric is efficiency, more than the cost of lumens, which requires identification of the loss mechanisms in light emission from LEDs.
Journal ArticleDOI

High-Efficiency Blue and True-Green-Emitting Laser Diodes Based on Non-c-Plane Oriented GaN Substrates

TL;DR: Using non-c-plane bulk GaN substrates, the authors demonstrate continuous-wave singlemode blue-emitting laser diodes operating with over 23% wall plug efficiency and over 750 mW output power, which represent the highest values reported to date.
Journal ArticleDOI

Determination of the first satellite valley energy in the conduction band of wurtzite GaN by near-band-gap photoemission spectroscopy

TL;DR: In this article, the position of the first satellite valley in wurtzite GaN is directly determined by nearband-gap photoemission spectroscopy of $p$-doped GaN activated to negative electron affinity.
