Aero-ZnS prepared by physical vapor transport on three-dimensional networks of sacrificial ZnO microtetrapods.

Aeromaterials represent a class of increasingly attractive materials for various applications. Among them, aero-ZnS has been produced by hydride vapor phase epitaxy on sacrificial ZnO templates consisting of networks of microtetrapods and has been proposed for microfluidic applications. In this paper, a cost-effective technological approach is proposed for the fabrication of aero-ZnS by using physical vapor transport with SnS crystals and networks of ZnO microtetrapods as precursors.

Spin-Coating and Aerosol Spray Pyrolysis Processed ZnMgO Films for UV Detector Applications.

A series of ZnMgO thin films with ranging from 0 to 0.8 were prepared by spin coating and aerosol spray pyrolysis deposition on Si and quartz substrates. The morphology, composition, nano-crystalline structure, and optical and vibration properties of the prepared films were studied using scanning electron microscopy (SEM), energy dispersive X-ray analysis (EDX), X-ray diffraction (XRD), and optical and Raman scattering spectroscopy.

Excitonic and electronic transitions in Me-SbSe structures.

The optical anisotropy of the SbSe crystals was investigated at 300 and 11 K. Excitonic features of four excitons (A, B, C, and D) were observed in the optical spectra of the SbSe single crystals and in the photoelectric spectra of the Me-SbSe structures. The exciton parameters, such as the ground ( = 1) and excited ( = 2) state positions and the binding energy (Ry), were determined.
