研究了硅单晶中磷施主束缚电子的自旋相干时间。这些样品是同位素控制的，因此它们可能具有不同浓度（从4.7%到99.2%）的Si-29，这是硅的唯一非零自旋稳定同位素。给出了电子自旋相干时间与取向的关系，并在时频空间分析了电子自旋回波包络调制。(c)2005 Elsevier B. V.保留所有权利。
We investigate spin coherence time of electrons bound to phosphorus donors in silicon single crystals. The samples are isotopically controlled so that they may possess various concentrations (from 4.7% to 99.2%) of Si-29, which is the only non-zero-spin stable isotope of silicon. The orientation dependence of electron-spin coherence times are presented, and electron spin echo envelope modulation is analyzed in time-frequency space. (c) 2005 Elsevier B.V. All rights reserved.
