氢气处理 meaning in Chinese
hydrogen gas processing
hydryzing
Examples
- Ohmic contacts on h2 - thermally - treated 6h - sic surface by evaporating aluminum without annealing have contact resistances of 8 10 - 3 - cm2 on room temperature and keep fairly good thermal stability under the temperature of 400 . its ohmic properties do n ' t depend on the doping concentrations of the substrate , which enables us to form ohmic contacts on low dropped substrate especially on epitaxial layer
通过氢气处理6h - sic表面并镀铝后直接形成的欧姆接触室温比电阻率达到8 10 ~ ( - 3 ) ? cm ~ 2 ，温度不超过400时该接触具有较好的稳定性，其欧姆特性不依赖于衬底的掺杂浓度，是一种适宜在低掺杂衬底特别是sic外延片上制备欧姆接触的有效方法。
