- Quantum Coffee Hour
- Time: 3:00 pm - 4:00 pm
- Place: Rm.5294, Chamberlin Hall
- Abstract: Please join us for the WQI Quantum Coffee today at 3PM in the Physics Faculty Lounge (Rm.5294 in Chamberlin Hall). This series, which takes place approximately every other Tuesday, aims to foster a casual and collaborative atmosphere where faculty, post-docs, students, and anyone with an interest in quantum information sciences can come together. There will be coffee and treats.
- Research Flash Presentation: Device Fabrication for Visualizing 2D Magnetism with Scanning Tunneling Microscopy and Spectroscopy
- Time: 4:00 pm - 4:15 pm
- Place: 5280 Chamberlin Hall
- Speaker: Siwei Wang, M.S. in Physics - Quantum Computing, UW-Madison
- Abstract: Scanning Tunneling Microscopy (STM) and Spectroscopy (STS) are promising techniques to visualize magnetism in 2D material with high spatial resolution. The atomic resolution of STM/STS has demanded an atomically clean surface for measurement. Fabricating atomically clean devices with the air-and photo- sensitive CrI3 2D magnet has been the bottleneck ever since the project’s perception. Techniques such as tip cleaning and annealing are able push out the bubbles, polymers and other defects generated in the fabrication process. In this talk I will discuss the efforts towards developing parameters for these techniques on the atomic force microscope and anneal chamber.
