SiC-YiG X波段量子传感器用于敏感表面顺磁共振应用于化学、生物、物理
SiC-YiG X band quantum sensor for sensitive surface paramagnetic resonance applied to chemistry, biology, physics
摘要：
在这里，我提出了SiC-YiG量子传感器，允许电子顺磁共振（EPR）研究单层或几纳米厚的化学，生物或物理样品位于传感器表面。它包含两个部分，一个4 H-SiC衬底与许多顺磁硅空位（V2）位于其表面下，和YIG亚铁磁性纳米带。自旋传感特性是基于纳米带在强磁场梯度下光学检测到的双电子-电子自旋共振。在这里，我描述了这种传感器的制造，磁性，光学和自旋传感特性。我表明，目标自旋灵敏度比标准X波段EPR光谱仪的灵敏度至少高五个数量级，因此，它与光纤束相结合，构成了灵敏表面EPR的强大升级。该传感器可以确定目标自旋平面EPR谱，它们的位置具有+/- 1 nm的纳米级精度，并且它们的2D浓度低至1/（20nm.20nm）。
英文摘要：
Here I present the SiC-YiG Quantum Sensor, allowing electron paramagnetic resonance (EPR) studies of monolayer or few nanometers thick chemical, biological or physical samples located on the sensor surface. It contains two parts, a 4H-SiC substrate with many paramagnetic silicon vacancies (V2) located below its surface, and YIG ferrimagnetic nanostripes. Spins sensing properties are based on optically detected double electron-electron spin resonance under the strong magnetic field gradient of nanostripes. Here I describe fabrication, magnetic, optical and spins sensing properties of this sensor. I show that the target spins sensitivity is at least five orders of magnitude larger than the one of standard X band EPR spectrometer, for which it constitutes, combined with a fiber bundle, a powerful upgrade for sensitive surface EPR. This sensor can determine the target spins planes EPR spectrum, their positions with a nanoscale precision of +/- 1 nm, and their 2D concentration down to 1/(20nm.20nm).
