Luminescent Properties of (004) Highly Oriented Cubic Zinc Blende ZnO Thin Films

Luminescent properties of BexCd1-xSe thin films

We report photoluminescence (PL) study of BexCd1KxSe epitaxial layers (x!0.21) grown by molecular beam epitaxy on InP substrates. Continuous wave PL spectra are taken within a 4.2–300 K temperature range. We observe an anomalous ‘s-shaped’ temperature dependence of emission energy and a severe decrease of emission intensity with the increase of temperature. We explain an ‘s-shaped’ temperature ...

Photoelectrochemical Properties of Highly Oriented ZnO Nanotube Array Films on ITO Substrates

Highly oriented ZnO nanotube array films on the conducting substrates have been synthesized by a simple hydrothermal method and characterized by scanning electron microscopy (SEM) and UV-Vis spectroscopy. The thin films consisting of laterally fragmentized ZnO nanotubes with controlled orientation have been tested as photoanode in Grätzel-type solar cell. For a sandwich-type cell, with 0.5 mol/...

Characterization of ZnO Thin Films

ZnO is a strategic material for various photonic applications. We present our results on characterization of thin films of ZnO grown by sol-gel spin and RF sputtering methods. The characterization techniques involved ellipsometry, scanning electron microscopy with energy dispersive analysis, X-ray diffraction and scanning tunneling microscopy. Microstructural characterization of the films using...
