摘要

我们记录了自旋子水平的反交叉光谱，并首次在用 0.9-MeV 电子或 15-MeV 质子辐照的市售 4H-SiC 肖特基二极管中发现了自旋-3/2 色心。研究显示了辐照密度对缺陷形成的影响。实验证明，质子辐照温度的升高会起到短期退火的作用，从而导致点缺陷浓度的降低。

Local Diagnostics of Spin Defects in Irradiated SiC Schottky Diodes

The spectra of anticrossing of spin sublevels have been recorded and spin-3/2 color centers have been identified for the first time in commercially available 4H-SiC Schottky diodes irradiated with 0.9-MeV electrons or 15-MeV protons. The effect of the irradiation density on the defect formation has been shown. It has been demonstrated that the increase in the temperature at which proton irradiation is carried out acts as a short-term annealing, leading to a decrease in the concentration of point defects.
