Crystallization of II-VI semiconductor compounds forming long microcrystalline linear assemblies

Abstract: In this work we report the formation of long microcrystalline linear self-assemblies observed during the thin film growth of several II-VI compounds. Polycrystalline CdTe, CdS, CdCO 3 , and nanocrystalline CdTe:Al thin films were prepared on glass substrates by different deposition techniques. In order to observe these crystalline formations in the polycrystalline materials, the thin film growth was suspended before the grains reached to form a continuous layer. The chains of semiconductor crystals were observ… Show more

“…Mostly, II-VI group materials have a direct band gap with high optical absorption coefficients, therefore absorption of around 99% of the impinged photon having energy higher than the band gap energy observed for a small layer thickness of ~1.0 μm [2,3]. Nowadays, these versatile semiconductor materials are applied extensively to electronic, optical, and photovoltaic devices including light-emitting diodes [4][5][6] thin-film transistors [7] optical waveguides [8] photodetectors [9] solar cells [10,11] and catalyst applications [12]. The cadmium and zinc-based groups of II-VI semiconductors (CdS, CdTe, CdSe, ZnS, ZnSe, ZnTe) have two main phases (i) zincblende and (ii) wurtzite in the bulk form [13].…”
