| Abstract | B-C-N compounds with different structures were synthesized by chemical reaction between Boracic acid and melamine, combined with heat treatment under vacuum and high pressure. An amorphous B-C-N precursor was prepared at 1273K under 10(-3) Pa. This amorphous B-C-N behaves as an insulator below 920K, and transforms into semiconductor above 920K. The B-C-N semiconductor shows different conductivity-temperature relationship in the temperature ranges of 973-1003K and 1013-1073K, and has conductivity activation energy of 0.34eV in the former range and 1.10eV in the latter range, indicating that conductivity mechanism of the B-C-N amorphous semiconductor is different in the two temperature ranges, Annealed for 40min. at 1473K under 3.5GPa, the amorphous B-C-N precursor crystallizes into hexagonal B-0.44 C-0.27 N-0.29 ( h-BCN) compound with lattice constants of a = 0.2515nm and c = 0.6684nm. Four strong Raman scattering peaks were observed at 1330, 1364, 1588 and 1617 cm(-1) in the h-BCN, of which the peaks located at 1330 and 1617 cm(-1) 1 are considered as characteristic Raman peaks of the h-BCN. |
