[𝗣𝗮𝗿𝗸 𝗞𝗻𝗼𝘄𝗹𝗲𝗱𝗴𝗲 𝗖𝗲𝗻𝘁𝗲𝗿] 𝗛𝗼𝘄 𝗔𝗙𝗠 𝘄𝗼𝗿𝗸𝘀: 𝗖𝗼𝗻𝘁𝗮𝗰𝘁 𝗠𝗼𝗱𝗲. In this video, you will learn about the most basic mode of Atomic Force Microscopy for measuring topography, the contact mode. These are the steps taken to map the topography in contact mode: 1️⃣ Approach & Engagement – The AFM tip moves toward the sample until it makes contact with the surface. 2️⃣Scanning & Deflection – The cantilever scans the surface while maintaining constant force, bending in resp
