Fine ceramics (advanced ceramics, advanced technical ceramics). Ultraviolet photoluminescence image test method for analysing polytypes of boron- and nitrogen-doped SiC crystals
精细陶瓷(高级陶瓷、高级工业陶瓷) 分析掺硼和掺氮碳化硅晶体多型性的紫外光致发光图像试验方法
This document specifies a test method for determining the polytypes and their ratios in silicon carbide
(SiC) wafers or bulk crystals using ultraviolet photoluminescence (UVPL) imaging. The range of SiC is
limited to semiconductor SiC doped with nitrogen and boron to have a deep acceptor level and a shallow
donor level, respectively. The SiC wafers or bulk crystals discussed in this document typically show
electrical resistivities ranging from 10—3ohm · cm to 10—2ohm · cm, applicable to power electronic
devices.All current amendments available at time of purchase are included with the purchase of this document.
