Custom Ultra-high-vacuum “suitcase” for the safe transfer of air-sensitive quantum materials and structures

这项提议是为了购买一个定制的超高真空样品运输系统，或称“真空行李箱”。这一装置将允许在推动UBC量子材料努力的关键实验设施之间轻松、可靠和安全地转移，在那里，这些新材料的表面和异质结构是以原子精度制备的。除了用分子束外延(MBE)生长薄膜和异质结的量子材料和器件铸造厂(QMDF)外，这还包括研究其动量和原子分辨电子结构的极具表面敏感性的技术，如达马塞利量子材料实验室(QML)的角度分辨光电子能谱(ARPES)、波恩和伯克的LAIR设施的扫描隧道谱，或Sawatzky新资助的量子材料电子显微镜中心。加拿大光源(CLS)的UBC光束线也将发挥关键作用，即自旋-ARPES量子材料光谱中心和共振弹性和非弹性X射线光谱光束线。

This proposal is for the purchase of a custom-made ultra-high vacuum sample-transport system, or “vacuum suitcase”. This device will allow easy, reliable, and secure transfer between the key experimental facilities that propel the quantum material effort at UBC, where surfaces and heterostructures of these novel materials are prepared with atomic precision. In addition to the Quantum Materials and Devices Foundry (QMDF) where films and heterostructures are grown by Molecular Beam Epitaxy (MBE), this include extremely surface sensitive techniques to study their momentum- and atomically-resolved electronic structure, such as Angle-Resolved Photoemission Spectroscopy (ARPES) in Damascelli’s Quantum Materials Laboratory (QML), Scanning Tunneling Spectroscopy in Bonn and Burke’s LAIR facility, or Sawatzky’s newly funded Quantum Materials Electron Microscopy Centre. A key role will be played also by the UBC beamlines at the Canadian Light Source (CLS), i.e. the Quantum Materials Spectroscopic Center for spin-ARPES and the Resonant Elastic and Inelastic X-Ray Spectroscopy beamline.
