摘要：
Bi2S3 whiskers ∼10 mm long were synthesized from vapor phase. The electrical conductivities of the resulting whiskers (along the longitudinal direction) were ∼101 S cm-1 at around room temperature and their temperature coefficient was negative. The growing direction was in the direction of the crystallographic c axis, which is parallel to the direction of running chains composed of (Bi4S 6)n. The measurements of electrical conductivities in sulfur-free and sulfur-loading atmosphere strongly suggest that carrier electrons are generated through the formation of sulfur deficiencies. © 1995 American Institute of Physics.
