Abstract:
Using the solution-melt method combined with the Bridgman method, CrS$_2$ single-crystal needles and single-crystal tubes are grown at a temperature lower than their melting (crystallization) temperature. Microcrystals thus grown feature an anomalously high thermal emf. The growth of CrSi$_2$ single-crystal tubes is an important step forward in the production of various devices based on high-temperature thermoelectric materials.
