Bachelor thesis/ Master thesis/ Diploma thesis
A major challenge for single-walled carbon nanotube (SWCNT) application in information technology, microelectronics and medicine represents chirality-selectivity. Among different synthesis methods for SWCNTs, catalytic CVD is the most promising one, because it provides high yields and mass-production ability. Moreover, lower process temperatures compared to laser ablation and arc discharge improve the selectivity. Predefined catalysts synthesized by physical vapor deposition (PVD) circumvent the exhausting optimization of parameters for in situ catalyst formation and enable the control of catalyst morphology and microstructure. In this thesis, catalysts for diameter- and chirality-selective growth of single-walled carbon nanotubes shall be developed and used for CVD growth of SWCNTs. State of the art characterization methods like Raman mapping, scanning and transmission electron microscopy and atomic force microscopy will be used for catalyst and nanotube characterization.
Department: Scaling phenomena (FWIO)
The thesis will be carried out in cooperation of Helmholtz-Zentrum Dresden-Rossendorf, TU Chemnitz and the Micro and Nanosystem group of ETH Zürich.
