金刚石紫外发光器件研究进展

蓝光或紫外激光在光电子学和光储存方面有广阔的应用，一直是国际上关注的前沿领域．而金刚石是最好的半导体紫外发光材料．特别是用于高温、高压、高功率、强辐射和强腐蚀环境中更能显示其优越性．目前人们已在实验上用同质外延、异质外延的方法制备了金刚石紫外发光二极管，观察到了较强的紫外光发射．人们尝试用金刚石与其他半导体材料结合的方法，成功地研制出了金刚石紫外发光二极管，开拓了该研究领域最新研究方向．文章对这些金刚石紫外发光器件研究的最新进展进行了评述．

Research and development of diamond ultraviolet light emitters

lue and ultraviolet lasers have numerous applications in optoelectronic devices and data storage. Diamond may be the ideal semiconductor material for ultraviolet light emission,especially as diamond devices can be used in high-temperature, high-pressure, chemically harsh and high-radiation-flux environments. Diamond ultraviolet light emitting diodes (LEDs) producing strong ultraviolet emission have been made by homoepitaxial and heteroepitaxial film growth in the laboratory. Recently, the combination of diamond with other semiconductor materials has opened up a new direction in this research field. We review the latest research and development of diamond ultraviolet LEDs.
