弱本地化(WL ) 大小在一张双性人装饰簇的 graphene 表被执行。费用集中被使经常,并且传导力修正的振幅在双性人簇免职以后被压制。当门和温度被改变时,详细 WL 数据被获得。用 E。McCanns 公式,纺纱松驰时间被提取,它被发现与散布时间的橡皮增加。这被归因于 Elliott-Yafet 旋转松驰并且 Kane-Mele 类型纺纱轨道联合(SOC ) 。SOC 力量由于第一免职被提高到 2.64 兆电子伏。范围效果在第二免职以后根据测量被讨论。
Weak-localization (WL) measurements were performed in a Bi cluster-decorated graphene sheet. The charge concentration was kept constant, and the amplitude of the conductance correction was sup- pressed after the Bi-cluster deposition. Detailed WL data were obtained while the gate and temperature were changed. Using E. McCamfs ibrmula, the spin-relaxation time was extracted, which was found to increase with the elastic scattering time. This is attributed to the Elliott-Yafet spin relaxation and Kane-Mele type spin--orbit coupling (SOC). The SOC strength was enhanced to 2.64 meV as a result of the first deposition. The coverage effect is discussed according to the measurement after tim second deposition.
