K Line Series ~10% As in Chinese supplement L lines not observed (1.28 and 1.32 keV - too low in energy to be excited) K α and K β energies are often close together (1.2 keV apart for As) K lines observed for low to medium Z elements (i.e., Cl, Fe, As) K α and K β s have typical ratio of ~ 5 to 1

Amorphous silicon - Wikipedia

Amorphous silicon (a-Si) is the non-crystalline form of silicon used for solar cells and thin-film transistors in LCDs. Used as semiconductor material for a-Si solar cells, or thin-film silicon solar cells, it is deposited in thin films onto a variety of flexible substrates, such as glass, metal and plastic. Amorphous silicon …

Hindawi - Densifiion and Microstructural Evolutions …

Porous SiC-Si-C ceramics were produced by reaction sintering (RS) of silicon carbide, silicon, and carbon powder compacts in the temperature range of 1400–1600°C. The effects of chemical composition of the starting powder, initial SiC particle size, and reaction sintering temperature and duration on the densifiion and microstructure of ceramic materials were studied
