| Sumario: | Nanomechanical systems have the potential to act as versatile platforms for the study of quantum phenomena. In this thesis the fabrication and application of a carbon nanotube (CNT) based charge sensor coupled to a double quantum dot (DQD) is investigated. Exploiting the unique electronic properties of CNTs, such as their high charge mobility and tunable bandstructure, our research showed that the CNT based charge sensor was able to detect changes in a DQD charge configuration. The project employed a chemical vapor deposition (CVD) technique for growth of CNTs. Experimental results showed that the sensor could resolve single electron motion. The findings demonstrate the potential of CNT-based sensors in detecting and analyzing quantum states. |
