Fabrication Of Horizontal Silicon Nanowires Using A Thin Aluminum Film As A Catalyst, Khaja Hafeezuddin Mohammed

Graduate Theses and Dissertations

Silicon nanowires have been the topic of research in recent years for their significant attention from the electronics industry to grow even smaller electronic devices. The semiconductor industry is built on silicon. Silicon nanowires can be the building blocks for future nanoelectronic devices. Various techniques have also been reported in fabricating the silicon nanowires. But most of the techniques reported, grow vertical silicon nanowires. In the semiconductor industry, integrated circuits are designed and fabricated in a horizontal architecture i.e. the device layout is flat compared to the substrate. When vertical silicon nanowires are introduced in the semiconductor industry, a whole …

Surface Pre-Treatments And Fabrication Of Highly Ordered Anodic Aluminum Oxide Nanopores At Room Temperature, Sampath Chennuri

Electrical & Computer Engineering Theses & Dissertations

The object of this work is to develop a novel approach to fabricate model membranes of well-defined and well aligned nanostructured materials in a robust environment. The main focus is on electrochemical synthesis, involving anodic oxidation of high purity aluminum sheets to form porous oxide films. Alumina films were prepared by anodizing highly pure aluminum (99.999%) in acidic electrolytes. Anodization parameters (current density, temperature, applied voltage, anodization time and electrolyte concentration) were selected with respect to the electrolyte used.

The primary challenge in nanotechnology is the creation of nanometer-scaled objects with as narrow a size distribution as possible for a …
