The Synthesis and Characterization of Individual and Hierarchically Structured Nanorod Materials
EMSL Project ID
2249
Abstract
The large-area and geometry of the unidirectionally aligned mesoporous silica is uniquely suited for the electrochemical deposition of interesting metallic, magnetic, and semiconductor nanorod materials. Since the nanorods will have the size and morphology of the mesopores, this provides the opportunity to fundamentally and systematically investigate the electrical, magnetic, and optical properties of supported-single and unsupported nanorod materials with diameter of ~ 10 unit cells to diameters in the macroscopic regime, and with aspect ratios up to 105. The hierarchically structured and matrix-supported nanorod materials will also be studied to explore how interfacial and matrix interactions influence physical properties. We will utilize wet synthetic techniques, TEM, and SEM to understand the relationship between the experimental variables described in the previous discussion and the resultant nanoscopic structures formed. We will also consider the electrochemical deposition studies to indirectly gain information about the continuity of the mesoporous structures.
