Conduction mechanisms in doped mixed-phase hydrogenated amorphous/nanocrystalline silicon thin films

Oxidation Effects in Rare Earth Doped Topological Insulator Thin Films

The breaking of time-reversal symmetry (TRS) in topological insulators is a prerequisite for unlocking their exotic properties and for observing the quantum anomalous Hall effect (QAHE). The incorporation of dopants which exhibit magnetic long-range order is the most promising approach for TRS-breaking. REBiTe3, wherein 50% of the Bi is substitutionally replaced by a RE atom (RE = Gd, Dy, and H...

An experimental and theoretical study on the physical properties of Al doped ZnO thin films

In this research, ZnO thin films with Al impurity as dopant were coated onto cleaned glass substrates by the spray pyrolysis technique. Crystal structure of the thin films was studied via XRD, and UV-vis spectroscopy was carried out to investigate their optical properties. Finally, in order to study the effect of Al impurity in ZnO thin films, the band structures of both pure and doped systems ...

Comparative Study of Nanostructured Zr-Fe2O3 and CNT Modified Zr-Fe2O3 Thin Films for Photo Electrochemical Generation of Hydrogen

Nanostructured hematite thin films are doped with zirconium successfully and also modified by introducing CNT using sol-gel method for their implementation as photo-electrode in photo-electrochemical (PEC) cell for hydrogen generation. XRD, UV-visible spectroscopy and PEC study techniques are used to characterize the thin films. The PEC responses of thin films are improved by introducing carbon...

investigation of contact poling process in thin films of polymer doped with disperse red 1 dye

thin films of polymer doped with nonlinear optical organic dye, disperse red 1, at thickness of 1 to 2 micrometers, were prepared and studied. in order to induce an axial and orientational alignment of dye molecules within polymer matrix, a contact electric field poling was used. by this process the inherent inversion symmetry in the polymer matrix was eliminated to achieve the desired macrosco...
