Process for growing Ge nanoline by aluminium oxide template

Abstract

A process for using alumina template to grow Ge nanowires includes such steps as preparing alumina template with multiple hexagonal cylinder holes by anodizing method, growing a gold layer as catalyst on the back of template, and growing Ge nanowires in gas-phase chemical deposition equipment, in which high-purity germane is used as growing gas source and nitrogen gas as protecting one, by reaction at 500-800 deg.C. Its advantage is controllable diameter and length.

AI Technical Summary

Benefits of technology

This invention relates to methods for making small metal particles with specific sizes that are very tiny (<100nm) or long enough to have their own unique properties like conductivity. These metals include germaniums, silicones, gold, silver, copper, iron oxide, zinc sulfate, selenium, vanadyl phosphorite, etc., which may help create electronic devices such as transistors and sensors.

Problems solved by technology

This patents discusses different ways how small germaniums could help make better electronic devices faster or less expensive. One way they tested was through reducing its dimensions down below 1 micrometer while maintaining certain characteristics like atomic number, lattice constants, etc., which makes them easier to manufacture. However, there were issues related to achieving these goals effectively without increasing costs significantly beyond what would otherwise be necessary due to physical limitations such as reduced device performance caused by miniaturization techniques.
