The reduction of surface “native” oxides from GaAs substrates following reactions with trimethylaluminum TMA precursor is studied using medium energy ion scattering spectroscopy MEIS and x-ray photoelectron spectroscopy XPS . MEIS measurements after one single TMA pulse show that 65% of the native oxide is reduced, confirmed by XPS measurement, and a 5 Å thick oxygen-rich aluminum oxide layer i...
Lightweight materials and related concepts have been progressively focused on as an important design topic in automotive industries. Lightweighting is also considered as one of the key solutions to assist the overcoming of barriers to electrification. Global trends toward reduction of greenhouse gas emissions and fuel economy have also significantly increased the importance of this topic over t...
in present study we studied using green routes for microwave assisted synthesis of alumina nanoparticles from aluminum nitrate. it was revealed that when plant extracts are used, no specific stabilizer is needed. structural characterization of nanoparticles was studied using x-ray diffraction that showed semi-crystalline structure for two of plant extracts, other xrd patterns had no significant...
