HRTEM study on the structure of Ge nanoparticles by using a UHV-MBE-TEM system

Abstract

Ge nanoparticles smaller than 4 nm in diameter were deposited on Si TEM samples and directly transferred into TEM using a UHV-MBE-TEM system. The structure of some nanoparticles was different from diamond structure. Some Ge nanocrystals even become amorphous and then fluctuate during HRTEM observation.
