How do Electron Microscopes Work? π¬π π¬ Taking Pictures of Atoms
The nanoscopic world is wild!! Looking at basic objects like a grain of salt under an electron microscope looks like nothing you would have expected. Furthermore, have you ever wondered whether seeing a single atom is possible? Or how do scientists and engineers create only a few nanometers wide transistors? In this video, we will explore the electron microscope and how they are used to see nanoscopic objects. Specifically, we'll look at the Transmission Electron Microscope and the Scanning Electron Microscope and dive into how they work.
