Two kinds of <111>-oriented b-SiC films with pyramidlike and needlelike morphologies were obtained by laser chemical vapor deposition. Their mean grain size () as a function of the distance from substrate (h) follows power laws of / h 0.62 and / h 0.71 , respectively. The planar defects in pyramidlike films were perpendicular to the growth direction, whereas those in needlelike b-SiC films inclined to growth direction, which can be annihilated with meeting of anti-couple defect. This self-vanish of defects would develop a new approach to fabricate high quality <111>-oriented b-SiC.G. Brennecka-contributing editor Manuscript No. 34552.
