Photoemission study of LT-GaAs
The electronic structure of GaAs (1 0 0) grown by low-temperature molecular beam epitaxy was investigated by means of photoemission spectroscopy. Slight differences are found in the valence band spectra of GaAs layers grown at different As2/Ga flux ratios. Analysis of As 3d [...]

•The performance of colloidal silica and ceria based slurries on CMP of 6H-SiC substrates were evaluated.
•There was a significant difference in the CMP performance of 6H-SiC between silica and ceria based slurries.
•For the ceria based slurries, a higher MRR was obtained, especially in strong [...]
