电探测固态系统自旋特性的能力是各种新兴技术的基础。在这里，我们用改进的哈恩回声序列证明了硅中磷供体的核自旋态的电读出。我们发现，虽然核自旋的电检测相相干时间超过2 ms，但它们仍然受到人为缩短的探测供体电子寿命的限制。©2012美国物理学会。
The ability to electrically probe the spin properties of solid state systems underlies a wide variety of emerging technologies. Here, we demonstrate the electrical readout of the nuclear spin states of phosphorus donors in silicon in the coherent regime with modified Hahn echo sequences. We find that while the nuclear spins have electrically detected phase coherence times exceeding 2 ms, they are nonetheless limited by the artificially shortened lifetime of the probing donor electron. © 2012 American Physical Society.
