摘要:

本文报道了在5.0K下,X波段脉冲电子核双共振(ENDOR)在掺磷硅中的电学探测。使用与常规电子自旋共振中的Davies ENDOR类似的脉冲序列来测量$^{31}$ P核自旋的核自旋跃迁频率,其中经由通过Si/SiO $_2$界面态的自旋相关跃迁来电检测$^{31}$ P电子自旋,因此不依赖于电子自旋系统的极化。此外,相干核自旋振荡的电检测示出,证明了电读出可能的核自旋量子比特的自旋状态的可行性。

英文摘要:

We demonstrate the electrical detection of pulsed X-band Electron Nuclear Double Resonance (ENDOR) in phosphorus-doped silicon at 5\,K. A pulse sequence analogous to Davies ENDOR in conventional electron spin resonance is used to measure the nuclear spin transition frequencies of the $^{31}$P nuclear spins, where the $^{31}$P electron spins are detected electrically via spin-dependent transitions through Si/SiO$_2$ interface states, thus not relying on a polarization of the electron spin system. In addition, the electrical detection of coherent nuclear spin oscillations is shown, demonstrating the feasibility to electrically read out the spin states of possible nuclear spin qubits.
