This project will involve the design, fabrication and measurement of nanoelectronic quantum circuits and thermometers based on single-electron devices. The coherence of quantum devices will be studied at low temperatures, and the same types of device will be used as thermometers for the on-chip electron temperature.The project will be undertaken in the Lancaster Quantum Technology Centre (LQTC) and Ultralow Temperature Physics group at Lancaster. An essential part of the work will be device fabrication using state-of-the-art nanofabrication facilities available in the LQTC cleanroom. The student will gain experience of working in a cleanroom environment and acquire practical skills in electron-beam and photolithography, thin-film deposition and plasma processing. They will be assisted by the experienced dedicated cleanroom technicians and academic staff who have expertise and hands-on experience in nanofabrication.

该项目将涉及基于单电子器件的纳米电子量子电路和温度计的设计、制造和测量。该项目将由兰开斯特量子技术中心（LQTC）和兰开斯特的超低温物理组承担，研究量子器件在低温下的相干性，并将使用相同类型的器件作为片上电子温度的温度计。这项工作的一个重要部分将是使用LQTC洁净室中最先进的纳米制造设施进行设备制造。学生将获得在洁净室环境中工作的经验，并获得电子束和光刻，薄膜沉积和等离子体处理的实践技能。他们将得到经验丰富的专用洁净室技术人员和学术人员的协助，他们在纳米纤维方面具有专业知识和实践经验。
