Zinc oxide (ZnO) nanorods grown by vapor transport were contacted individually with Ti/Au electrodes structured by e-beam lithography. The rectifying behaviour observed in the current-voltage characteristics is likely caused by an interfacial insulat

We have deposited and characterised ZnO on flexible and transparent plastic polymer. We employed a specially designed vapour phase growth system with elemental sources for zinc and oxygen and deposited thin ZnO films at temperatures below 400 °C. Ba

The quality of the ZnO films, epitaxially grown on sapphire, can be substantially improved when a MgO buffer layer is used. The role and the structural characteristics of this buffer layer were studied by transmission electron microscopy. It was foun

We report on the growth and characterization of n-ZnO/p-4H-SiC heterojunction diodes. Our n-ZnO layers were grown with radical-source molecular beam epitaxy (RS-MBE) on p-4H-SiC epilayers, which was previously prepared in a horizontal hot-wall reacto

Optical properties of ZnO-based single nanorods are probed by cathodoluminescence (CL) measurements at T = 5 K. We observe a variation of the ZnO near band edge CL by three orders of magnitude along the nanorod axis, accompanied by a spectral blueshi

Zinc oxide (ZnO) nanorods were grown by a wet chemical approach and by vapor phase transport. To explore the electrical properties of individual nanostructures current-voltage (I-V) characteristics were obtained by using an atomic force microscope (A

We report on the fabrication of high performance InP-based devices on an exact (001)Si-substrate. On an InP-on-Si quasi-substrate, the growth of superlattices and low-temperature InAlAs buffer for surface and device layer improvement is investigated.

ZnO thin films, ZnMgO/ZnO heterostructures and ZnO nanostructures were fabricated using molecular beam epitaxy (MBE), vapour phase transport (VPT) and an aqueous chemical growth approach (ACG). The possibility to employ several fabrication techniques

ZnO nanorod-based single quantum well heterostructures were fabricated in a two-step process. Nanorods were first grown using vapour transport. Subsequently, high-quality ZnO/Zn0.85Mg0.15O heterostructures were grown on the nanorods using molecular b
