Characterization and cleaning of aligned CNTs
Leuven | More than two weeks ago
Carbon nanotubes (CNT) are considered as alternative channel material for beyond CMOS transistors, offering significant advantages over Si and 2D materials. For proper device construction, CNTs are aligned using chemical methods, leaving some polymer encapsulation which needs to be removed. Similarly, e-beam resist used for photolithography also leaves residues attached to the CNTs. Finally, it is known that CNTs have relatively high surface area and consequently adsorb hydrocarbons during fabrication and from the ambient air.
This project is designed to contribute to better fabrication of aligned CNT-based nano-devices by exploring cleaning methods:
- Heat treatment in various ambient and wide temperature range
- Remote plasma H2 plasma
- UV cure
The samples will be evaluated using several techniques including: WCA, AFM, Raman spectroscopy.
