Ambipolar behavior of Te and its effect on the optical emission of ZnO: Te epitaxial thin film

Sahu, R.; Dileep, K.; Negi, D. S.; Nagaraja, K. K.; Datta, Ranjan (Wiley-V C H Verlag Gmbh, 2015)

We present control over the ambipolar nature of Te in ZnO and the corresponding optical band gap in epitaxial thin film grown by pulsed laser deposition. Experimentally, the decrease in band gap is found to be strongly ...
Crystallographic phase separation and band gap of ZnO1-xSx (x=0.1-0.3) alloy thin films grown by pulsed laser deposition

Dileep, K.; Sahu, R.; Nagaraja, K. K.; Datta, Ranjan (Elsevier Science Bv, 2014)

Crystallographic phase separation and optical properties of ZnO1-xSx (x=0.1-0.3) alloy thin films grown by pulsed laser deposition (PLD) on c-plane sapphire substrate have been investigated with and without using ZnO buffer ...
Spontaneous growth of InxGa1-xN nanostructures directly on c-plane sapphire by plasma assisted molecular beam epitaxy

De, Arpan; Nagaraja, K. K.; Tangi, Malleswararao; Shivaprasad, S. M. (IoP Publishing Ltd, 2014)

Effect of growth temperature on the morphology, structural and optical properties of InxGa1-xN layers grown under nitrogen-rich conditions, by plasma assisted molecular beam epitaxy, on c-plane Sapphire have been studied. ...
Structural and optical property characterization of epitaxial ZnO:Te thin films grown by pulsed laser deposition

Sahu, R.; Dileep, K.; Negi, D. S.; Nagaraja, K. K.; Shetty, S.; Datta, Ranjan (Elsevier Science Bv, )

We have investigated the Te atom incorporation, solubility, structural features and the corresponding optical property of epitaxial ZnO:Te thin film grown on c-plane sapphire by pulsed laser deposition. Incorporation of ...
