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 ...

Auger electron spectroscopy (AES) is an incredibly useful technique for probing material samples—but current assumptions about the process ignore some of the key time-dependent effects it involves. So ...

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 ...

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 ...

Two-dimensional (2D) perovskites are multiple quantum well (QW) structures formed by alternating inorganic and organic layers. They are promising in applications of solar cells, LEDs, and ...

Auger electron spectroscopy is a well-established surface-sensitive technique. It has been mostly used for the identification of species on sample surfaces, especially to monitor the process of sample ...

Jitter free: artistic depiction of a self-referencing attosecond streaking experiment. The inherent delay between the emission of the two types of electron leads to a characteristic ellipse in the ...

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 ...

(Nanowerk News) A new computational approach makes more realistic assumptions about the redistribution of energy during the Auger process, improving the accuracy of Auger electron spectroscopy. Auger ...
