Secondary Ion Mass Spectroscopy study of transitions metals doped ZnO nanowires
EMSL Project ID
27792
Abstract
This proposal is aimed at the study of the structural properties of electrodeposited doped-ZnO nanowires using Secondary Ion Mass Spectroscopy (SIMS). ZnO is significant because of its wide-band gap (3.37eV) and large exciton binding energy (60meV), which could lead to room temperature photonic device fabrication [1-7]. Although research focusing on ZnO goes back many decades, the renewed interest is fueled by the availability of high-quality substrates and reports of p-type conduction, ferromagnetic behavior and spintronics applications when doped with transitions metals, which remains controversial. In this proposal, we would like to use SIMS measurements to confirm the incorporation of various transitions metal ions (Al, Cu, Co, Mn and Ni) which were added to the electrolyte in known concentrations during the electrochemical growth process.
