【Abstract】 The type-Ⅱb diamond has excellent semiconducting properties. It can be used in the electric or electronic devices and works well in the higher temperature and worse environment. It has been accepted that the diamond was a promising semiconducting material of high temperature and power. So the recent development of some aspects of the diamond, such as structure, synthesis, semiconducting characteristics and application were summarized in this paper, and at the same time the developing and research directions of the type-Ⅱb diamond in the future are put forward.更多还原
