ABSTRACTWe have modified a conventional dimpling machine to perform chemical polishing with a reactive etchant. The modified dimpler also detects specimen perforation in situ optically, and automatically stops the dimpling process by lifting the dimpler wheel and flooding the specimen with a rinse solution. Using this apparatus, we are able to prepare both planar and cross-sectional thin specimens of compound semiconductor materials without using expensive and time-consuming ion-milling. The specimens have large thin areas, are free of artifacts, and are suitable for high-resolution lattice imaging.

This work focuses on synthesis of MWCNT-alumina hybrid compound via methane decomposition process using nickel catalyst. The catalysts prepared through in situ process by using nickel salt and aluminium powder which then calcined at 900oC followed by methane decomposition process to grow MWCNT on alumina surface. The Scanning Electron Microscopy (SEM) and High Resolution Transmission Electron Microscopy (HRTEM) images confirmed the formation of MWCNT with homogenous dispersion on alumina particles.
