Experimental evidence of a size-dependent sign change of the Seebeck coefficient of Bi nanowire arrays
Abstract The electrical transport in bismuth nanowires is strongly influenced by both sample geometry and crystallinity. Compared to bulk bismuth, the electrical transport in nanowires is dominated by size effects and influenced by surface states, which gain increasing relevance with increasing surf...
