Optical Characterization of GaN

201931&ensp·&enspGallium Nitride is a group IIIV compound semiconductor with a direct bandgap of 3.4 eV. Its wide bandgap has made it a popular material for optoelectronic devices such as LEDs, lasers and high power, high frequency and efficient electronic devices [1]. Only until recently it was discovered how to successfully grow GaN films on silicon substrates,

Epitaxial growth of gallium nitride by ionbeamassisted

The epitaxial growth of gallium nitride thin film was obtained on the inclined Si(111) substrates by the process of ionbeamassisted evaporation (IBAE) at the low temperature of 500 °C. The film composition determined by Rutherford backstering spectrometry shows that the synthesized film is a stoichiometric nitride.

Poisson noise removal from highresolution STEM images

Abstract. Scanning transmission electron microscopy (STEM) provides subångstrom, atomic resolution images of crystalline structures. However, in many appliions, the ability to extract information such as atom positions, from such electron micrographs, is severely obstructed by low signaltonoise ratios of the acquired images resulting from necessary limitations to the electron dose.

Experimentos com dopagem com berílio foram realizados no final da década de 1990, na esperança de que o berílio se mostrasse mais eficiente como agente de doping do que o magnésio predominante usado em lâmpadas de LED. O trabalho não teve sucesso, no entanto, e a pesquisa sobre berílio foi amplamente descartada.
