Development of the Carbon-nanotube Double Quantum dot for Room Temperature Terahertz Detector

点击翻译按钮获取中文摘要

In this project, the Single Walled Carbon Nanotube Double Quantum Dot was fabricated by atomic layer deposition and electron beam irradiation for the high-temperature and high-sensitivity THz detectors. The tunneling barriers were controlled by irradiation dose and insulating layer thickness. These samples were measured at low temperature transport measurement system with optical windows for THz wave range. Moreover, the HfO2 covered DWCNT transport properties were also investigated at room temperature and low temperature.
