Copper is vital for human health in minute amounts, but rapid and excessive intake of it from drinking water can cause short-term gastrointestinal disturbance. Long-term exposure to copper higher than 1.3 ppm over many years can cause kidney and liver damage. For this reason, in…
In this dissertation, we investigated a vapor-liquid-solid (VLS) synthesis of high-density lead sulfide (PbS) NW arrays and nano pine trees directly on Ti thin films, and a fabrication of photovoltaic devices based upon the PbS NWs. The as-grown NW arrays are largely vertically …
Limitation of near future scaling down of conventional silicon technology stimulated the quest for alternative technologies in nanometer-scale materials and devices in recent years. Since the discovery of carbon nanotubes, there has been great interest in the synthesis and chara…
In this dissertation, the characterization of magnetically doped amorphous semiconductors and self-assembly nanowires is described. The structure and morphology of Gd-Si, Gd-Ge, Gd-Al-Si, Gd-C, Nb-Si, Nb-C, and Co-Si magnetically doped amorphous semiconductors have been evaluate…
