Hexagonal CdTe-like rods prompted from Bi₂Te₃ droplets

In this work, we show the formation of hexagonal CdTe rods prompted by Bi₂Te₃ droplets fabricated by a whiskered vapor-liquid-solid growth process. Several techniques such us photoluminescence, cathodoluminescence, and scanning electron microscopy have been used to show their existence and their hexagonal crystalline phase. These hexagonal rods are proposed as the possible basis of new textured CdTe based solar cells.
