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 ...

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 ...

AES operates on the principle of the Auger effect, named after the French physicist Pierre Auger. When a material's surface is bombarded with a beam of high-energy electrons or photons, it causes the ...

What is Auger Electron Spectroscopy (AES)? Analyzing the features of various types of substrates involves the application of the essential analytical technique known as Auger Electron Spectroscopy ...

Researchers at UCSB say they’ve figured out the cause of a problem that has made light-emitting diodes (LEDs) impractical for general lighting purposes. Their work will help engineers develop a new ...

High-voltage and high-power devices are critical for more efficient and sustainable high-power operations. One candidate for such next-generation devices is bipolar silicon carbide (SiC). SiC devices ...

In an international research collaboration between Tsinghua University in Beijing and Sorbonne University in Paris, scientists found that four hydrocarbon molecules, known for their internal ring ...
