Nanomaterials are of great interest for a variety of practical applications. To achieve improved performance of nanomaterial-based devices it is essential to understand and modify their surface properties. Here we present an investigation of properties of nanosurfaces of ZnO and TiO2, and discuss their applications in photovoltaics and antibacterial coatings.
The zinc oxide (ZnO) nanostructure grown onto the carbon nanotube (CNT) surface could enhance the CNT FE characteristics. However, the ZnO nanostructure morphology is an important parameter to decide the FE enhancement. This study used thermal chemical vapor deposition (TCVD) to form ZnO nanostructure onto CNT bundle surface, and adjust the distance (D) between the CNT bundle and the zinc acetate...
For the past decade TNO has been involved in the research and development of atmospheric pressure CVD (APCVD) and plasma enhanced CVD (PECVD) processes for deposition of transparent conductive oxides (TCO), such as tin oxide and zinc oxide. The use of atmospheric deposition processes allows for large scale roll to roll manufacturing, and is therefore expected to provide a breakthrough for lowering...
ZnTe is a candidate low-cost II-VI absorber material of wide band gap (EG = 2.24 eV) with potential of enhanced open circuit voltage and application for tandem cells. Fundamental chemical and electronic properties related to the processing of ZnTe-based devices are demonstrated. We used x-ray diffraction, scanning electron microscopy and photoemission spectroscopy to analyze film structure, morphology,...
