项目摘要

We have doped rare-earth(RE) elements to III-V semiconductors using atomically-controlled crystal-growth techniques and investigated luminescent and magnetic properties due to RE ions. Ultrafast energy transfer from the host to RE ions was revealed in the materials. The first demonstration of red emission was succeeded in a nitride-based light-emitting diode with Eu-doped GaN. The room-temperature ferromagnetism was proved to be induced by carriers. The feasibility to develop new opto-magnetic devices was also confirmed.
我们使用原子控制晶体生长技术将稀土 (RE) 元素掺杂到 III-V 族半导体中,并研究了稀土离子引起的发光和磁性。该材料揭示了从主体到稀土离子的超快能量转移。红光发射的首次演示在具有 Eu 掺杂 GaN 的氮化物基发光二极管中获得成功。室温铁磁性被证明是由载流子引起的。开发新型光磁器件的可行性也得到了证实。
