“…Zinc oxide (ZnO) has been considered as a promising candidate material in ultraviolet (UV) photodetectors due to its wide bandgap, high electron saturation velocity and high radiation resistance, etc. 1–8. By alloying with MgO, the bandgap of ZnO can be tuned from 3.37 eV to 7.8 eV, which corresponds to a wavelength range of 160–370 nm 9, 10.…”

MgZnO‐based ultraviolet avalanche photodetectors (APDs) have been fabricated from Au/MgO/Mg0.44Zn0.56O/MgO/Au Schottky structures. The carrier avalanche multiplication is realized via an impact ionization process occurring in the MgO layer under relatively large electric field. The APDs exhibit an avalanche gain of 587 at 31 V bias, and the response speed of the APDs is in the order of microseconds.magnified image(© 2013 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

Abstract. For the first time, Cu-Al-O films were grown using the reactive ion beam sputtering at temperatures ranging from 80 to 380 °C in 50 °C increments. Correlations between the properties of as-grown films measured by X-ray diffraction, energy dispersive X-ray spectroscopy, atomic force microscopy, Fourier transform infrared spectrometry and optical transmission measurements have been discussed. It was shown that the increase of substrate temperature caused formation of the CuAlO 2 phase. Additional optimization of technological parameters of growth and post-growth temperature annealing are necessary to obtain single-phase CuAlO 2 films.

“…The nature of this mode is still thoroughly unknown. The mode at 275 cm −1 was found in Raman spectra of doped ZnO by nitrogen [17][18][19], by Al-N [20], and by Fe, Sb, Al, Ga, and Li [21]. This mode also appears in the Raman spectra of undoped ZnO films [22].…”

Abstract:For the first time, we present a novel method of explosive evaporation (MEE) for the deposition of ZnO nanostructures using concentrated solar radiation for precursor evaporation. Zinc acetylacetonate powder and a mixture of ZnO with graphite powders are used as precursors for the deposition of ZnO nanostructures. ZnO nanostructures are deposited on Au/Si, Ag/Si, and unpolished Si substrates by MEE. The scanning electron microscopy, energy dispersive X-ray analysis, X-ray diffraction, Raman scattering, photoluminescence, and Fourier transformed infrared spectroscopy are used for sample characterization. We demonstrate that the changing of precursors and the substrate types allows ZnO nanostructures to be grown with diverse morphologies: hexagons, spheres, and needles. The properties of ZnO nanostructures deposited on unpolished, coated by Ag and Au silicon substrates are discussed. MME using concentrated solar radiation is promising method for applications in the semiconductor industry as an economically efficient environmentally-friendly method for the growth of nanostructures.
