WebUV Cutoff. As the transmission curve in below illustrates, GE Type 214 fused quartz has a UV cutoff (1 mm thickness) at < 160 nm, a small absorption at 245 nm and no appreciable absorption due to hydroxyl ions. Type 219, which contains approximately 100 ppm Ti, has a UV cutoff at ~230 nm for a 1 mm thick sample. WebDec 15, 2007 · Section snippets Experimental. Two groups of Cz-Si samples doped with phosphorus in concentrations [P]=(1–2)×10 14 cm −3 were used. The first group was strongly doped with Ge in concentrations of about 2×10 20 cm −3 and the second one contains Ge impurity atoms in concentrations ⩽10 17 cm −3 as a background impurity. …

WebJan 20, 2024 · Several O–H and O–D vibrational lines for complexes that involve impurities that are shallow donors and deep acceptors have been reported recently. The present article compares and contrasts the vibrational properties of complexes that involve shallow donors (OD-Si and OD-Ge) with complexes that involve deep acceptors (OD-Fe and OD-Mg). WebJul 5, 2024 · When a semiconductor is doped with a Group V impurity it is called an n-type material, because it now contains a surplus of n egatively charged electrons not bonded to the surrounding semiconductor atoms. In an n-type semiconductor, the majority carrier, or the more abundant charge carrier, is the electron, and the minority carrier, or the less ...
