Abstrakt:	The p-type BiTe thermoelectric materials made by zone-melting method exhibit high anisotropy in the mechanical/thermoelectric properties due to unidirectional crystal growth. This unidirectional crystal structure also has a strong effect on the Sn/ p-BiTe interfacial reactions. Stripe-like SnSb phase precipitated in the SnTe phase in a direction approximately perpendicular or parallel to the Sn/ p-BiTe interface depending upon the p-BiTe crystal orientation. Such anisotropic growth behavior of the SnSb phase significantly affected the SnTe phase growth. [ABSTRACT FROM AUTHOR]
