Abstract:

Sn1–x Pb x S (0.08 ≤ x ≤ 0.16) thin films and whiskers with orthorhombic crystal structure of α-SnS were produced by hot wall vacuum deposition method (HWVD). The whiskers grew via a self-consuming vapor–liquid–solid (VLS) mechanism by means of Sn-droplets onto the surface of an underlying thin film which is build by differently oriented blocks. As revealed by transmission electron microscopy (TEM) and energy dispersive X-ray spectroscopy (EDX) experiments there is no composition gradient across the whiskers and the underlying thin film. TEM and X-ray analysis showed that the whiskers and polycrystalline thin films have a preferential orientation along [001] perpendicular to the substrate surface. Scanning electron microscopy investigations indicate a strong dependence of whiskers growth on the lead concentration and substrate temperature. Increasing Pb content the substrate temperature has to be increased to realize whisker growth via VLS.
