WebSep 9, 2024 · In this paper, we described a method of double-sided diffusion and drift of lithium-ions into monocrystalline silicon for the formation of the large-sized, p-i-n structured Si(Li) radiation detectors. The p-i-n structure is a p-n junction with a doped region, where the “i-region” is between the n and the p layers. A well-defined i-region is usually associated … http://www.topsil.com/media/123119/hires_application_note_v1.1_january2014.pdf

WebFloat Zone Wafers (FZ) Silicon Valley Microelectronics offers float zone (FZ) wafers ranging in diameter from 50mm to 200mm. These wafers have a low concentration of impurities and high-temperature capabilities. The properties of FZ wafers give them advantages over CZ wafers in a variety of applications. Low Resistivity Wafers WebWith efficiencies near 25%, float zone wafers are the high purity alternative to wafers that use silicon grown by the Czochralski (CZ) method. In addition to being extremely pure, … WebThe main advantage of the float-zone technique is the very low impurity concentration in the silicon crystal. In particular the oxygen and carbon concentration are much lower as compared to CZ silicon, since the melt … how did redd foxx die
