Growth of one-dimensional nanomaterials in the ETEM
Jonathan P. Winterstein, Renu Sharma
One-dimensional nanomaterials (nanowires and nanotubes) have a number of unique and interesting properties that have made them the subject of significant research for a wide range of applications. Electron microscopy is generally necessary for their morphological, structural and chemical characterization due to the small dimensions. For most applications, such as nano manufacturing and nano electronics, their synthesis must be part of scalable device fabrication process that requires a stringent control on process parameters. Catalytic chemical vapor deposition (CVD) is currently the most suitable route that allows their selective, aligned and scalable growth directly on a substrate. Characterization of growth parameters and atomistic growth mechanisms is necessary if such nanomaterials are to be engineered for devices with specific applications. Environmental transmission or scanning transmission electron microscopy (ETEM or ESTEM) provides the needed platform for in situ monitoring of the influence of processing parameters on their structure and morphology. In this chapter we present the practical aspects of experiment design, data analysis, successful examples, and the limitations of the ETEM platform to follow the one-dimensional nanomaterial growth processes.
