Acquisition of a controlled environment fabrication system for two-dimensional materials
Abstract
Two-dimensional materials hold tremendous promise for a range of applications from electronics to photonics. By combining and layering different two?dimensional crystals, new artificial materials can be created that will host new physics and ultimately lead to new types of electronic and opto-electronic devices. The fabrication of these artificial materials requires the sequential identification and stacking of individual 2D layers. This is accomplished using a van der Waals stamping technique where individual flakes are picked up on a polymer stamp. Then, additional flakes are picked up using a probe station with control over the position and rotation of the materials. Currently, this process takes place in the ambient environment of a lab. However, many of the newly discovered 2D materials such as the semiconductor, superconductors and ferromagnets are oxygen sensitive. Therefore, the fabrication of the van der Waals heterostructure devices with these materials needs to take place in a controlled oxygen?free environment. This proposal requests funds to purchase a glove box and probe station so that heterostructures can be fabricated in an oxygen-free environment. This instrumentation will enable higher quality devices which will lead to the discovery of new physical phenomena.
