Electronic structure of the nitrogen donors in 6H SiC as studied by pulsed ENDOR and TRIPLE ENDOR spectroscopy

Popis výsledku v původním jazyce

The nitrogen (N) donors in 6H SiC were investigated by field sweep electron spin echo (FS ESE), pulsed electron nuclear double resonance (ENDOR) and pulsed General TRIPLE ENDOR spectroscopy. The 29Si and 13C superhyperfine (shf) lines observed in the FSESE and ENDOR spectra of N in n-type 6H SiC were assigned by pulsed General TRIPLE resonance spectroscopy to the specific carbon (C) and silicon (Si) atoms located in the environment of N donors residing at two quasi-cubic lattice sites (Nk1, Nk2) in 6HSiC. As a result, the largest value of the shf interaction was found with Si atoms for the N donors at the hexagonal (Nh) and quasi-cubic site Nk1, while for Nk2 the largest value of the shf interaction was found with C atoms. It gives us the argument toconsider that N substitute different lattice sites in 6H SiC lattice. The relative signs of the shf interaction (shfi) constants for Nk1 and Nk2 with 29Si and 13C nuclei located in the nearest-neighbor.
