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.

本项目采用原子层沉积和电子束辐照的方法制备了单壁碳纳米管双量子点，用于高温、高灵敏度的太赫兹探测器。隧道势垒由辐照剂量和绝缘层厚度控制。这些样品是在具有太赫兹波段光学窗口的低温输运测量系统上测量的。此外，还研究了HfO2包覆的多壁碳纳米管在室温和低温下的传输特性。
