Defects often limit the performance of devices such as light-emitting diodes (LEDs). The mechanisms by which defects annihilate charge carriers are well understood in materials that emit light at red ...

Indium gallium nitride (InGaN)-based, blue-light-emitting diodes are the backbone of solid-state lighting (SSL). Unfortunately, their efficiency peaks under low current densities (<35 A/cm 2) and ...

While there are a number of techniques available for profiling surface structures, like scanning electron microscopy and transmission electron microscopy, the advantage Auger spectroscopy has for ...
