Week 2Molybdenum disulfide Fox
Tan Dao This is an image of a mechanically exfoliated molybdenum disulfide (MoS2) flake on a silicon dioxide substrate that happens to look similar to a fox sitting on a rock. Week 3
Rainbow Road
Page Waldo This is an image of polycarbonate film melting onto a silicon dioxide substrate. Currently in the Hollen lab we are experimenting with the transfer and stacking of 2D flakes to create unique heterostructures. This image was taken during a first attempt to pick up flakes of molybdenum disulfide grown on SiO2 by chemical vapor deposition. We learned that extraneous dust and wrinkles in the PC film don't help the process, but they do make for a beautiful optical image. |
Week 4
Bending Into Itself Quintin Watson These images were created using Feenstra's tip induced band bending simulation program. In Hollen Lab, we are studying how TIBB affects scanning tunneling spectroscopy. In the top left, the figure shows the amount of BB that occurs for Black Phosphorus, for a specific tip-sample separation. The amount of BB is represented by the brightness in that region, with Tip-Sample bias on the vertical axis and radial distance on the horizontal. The next two figures are a gray scale image and a binary image of the original. The final figure maps the boundary in the binary image, which coincidentally looks like the very thing that caused the band bending; a tip. |
