Exploring the NanoWorld with Professor Wee! - STEM, Here and Now EP2 [STM/AFM]

In this video, Professor Andrew Wee Thye Shen will bring us on an expedition to visit the NanoWorld! We will be exploring the technologies used in Scanning Tunneling Microscopy (STM) and Atomic Force Microscopy (AFM) at the National University of Singapore (NUS) Surface Science Laboratory (Physics). For more info please visit: NUS Physics Department: https://www.physics.nus.edu.sg/ NUS Surface Science Laboratory: https://www.physics.nus.edu.sg/~surface/ More info from the video: Tunneling Current: In Quantum Mechanics, a tunneling current occurs when electrons move through a barrier that they classically should not be able to move through. Baking Method (Degassing): A process of using high heat temperature and possibly vacuum, to remove contaminants from the material before placing them into situations where the slow release of the same contaminants would contaminate the contents of a container or vessel (contaminating the vacuum environment), resulting in the inaccurate measurement result.
