Electrical Properties of p-Si/n-ZnO Nanowires Heterojunction Devices

This paper explores the temperature dependent h terojunction beh vi r of n-type zinc oxide (ZnO) nanowires/pSi diodes. The device behavior at different temperatures in forward as well as reverse biased conditions are studied and reported. From the detailed electrical properties, it is confirmed that the fabricated p–n diode showed a good stability over the temperature range of 25–130 C. The tur...

Synthesis and characterization of Ag-doped p-type ZnO nanowires

P-type ZnO nanowires with silver (Ag) doping were synthesized via a chemical vapor deposition process. The incorporation of Ag was confirmed by selected-area energy-dispersive x-ray spectroscopy. The formation of acceptor states was demonstrated by temperature and excitation power-dependent photoluminescence measurements. Characterization of field-effect transistors using Ag-doped ZnO nanowires...

Synthesis and gas sensing properties of membrane template-grown hollow ZnO nanowires

One-dimensional, hollow nanostructured materials are among the most promising materials for sensing applications owing to their high surface area that facilitates the adsorption of target gases. Accordingly, for gas sensing studies, hollow ZnO nanowires (NWs) with different surface areas were successfully synthesized herein by using polycarbonate membranes with different pore sizes as templates...

Synthesis and magnetic properties of Mn doped ZnO nanowires

Mn doped ZnO nanowires have been synthesized using a simple autocombustion method. The as-synthesized Mn doped ZnO nanowires were characterized by X-ray diffraction and transmission electron microscopy. An increase in the hexagonal lattice parameters of ZnO is observed on increasing the Mn concentration. Optical absorption studies show an increment in the band gap with increasing Mn content, an...
