J. Piątkowski The Silesian University of Technology, Faculty of Materials Science and Metallurgy, Katowice, Poland R. Wieszała, The Silesian University of Technology, Faculty of Transport, Katowice, Poland The paper presents microstructure tests of alloy AlSi17Cu5. In order to disintegrate the primary grain of silicon the so-called time-temperature transformation TTT was applied which was based...
This paper characterizes the surface modification on silicon surfaces with different patterns (circle, pyramid) using a nanosecond fiber laser parameters, which enhances its anti-reflection property. The influence of textured and untextured their structural properties were evaluated. It has long absorption path (200–1000 nm) rougher due to modifications, results in 40% decrease incident light r...
IMMOBLIZATION OF BIOLOGICAL MATTER USING TRANSPARENT METAL ELECTRODES AND SILICON MICROSTRUCTURES Bharat Sankaran, B.S. George Mason University, 2006 Thesis Director: Dr. V. Rao Mulpuri This thesis describes the development of two different methods to produce an optimal platform for immobilizing biological matter (cells and proteins). Firstly, transparent indium tin oxide (ITO) microelectrodes ...
