我们利用单频激光、光致发光激发光谱以及光电流光谱分析了高富集28Si的明显的束缚激子跃迁。311p给体光谱中分辨率较高的双重态反映了电子和核给体自旋的超精细耦合。核自旋态的光学检测，以及特定电子和核自旋态的选择性抽运和电离给体，为实现硅基量子计算机提供了许多新的可能性。
We resolve the remarkably sharp bound exciton transitions of highly enriched 28Si using a single-frequency laser and photoluminescence excitation spectroscopy, as well as photocurrent spectroscopy. Well-resolved doublets in the spectrum of the 31P donor reflect the hyperfine coupling of the electronic and nuclear donor spins. The optical detection of the nuclear spin state, and selective pumping and ionization of donors in specific electronic and nuclear spin states, suggests a number of new possibilities which could be useful for the realization of silicon-based quantum computers.
