Magnetic resonance study of p-Type 3C SiC microparticles
Original language description
The silicon carbide (SiC) 3C polytype microparticles with p-type conductivity are investigated by X-band electron paramagnetic resonance (EPR) technique in a wide temperature interval. Morphological and Raman studies show that the mean particle diameter is 8 μm, and the SiC polytype is purely 3C. At T ¼ 10 K,the EPR spectrum of the shallow boron acceptor substituting cubic site (BK), with C3V symmetry and anisotropic g- and A-tensors resulting from static Jahn–Teller effect, is observed. At T >30 K, a continuous transition from static to dynamic Jahn–Teller effect for BK is detected. The temperature-dependent BK principal gvalues are explained by the transitions between the ground and excited vibronic states of BK. At T ¼ 130–150 K, the BK center is characterized by Td symmetry and isotropic g- and A-tensors. At T ¼ 60–190 K, an additional single EPR Lorentzian line with short spin relaxation times and isotropic g-value close to BK average gvalue is observed.
