Atomic Force Microscopy (AFM) and Scanning Tunneling Microscopy (STM) are two very efficient techniques for examining materials at the atomic and molecular levels. AFM works on the interaction forces between the tip and the sample surface. STM is a sort of microscopy that scans the surface of a sample using a conductive tip. While AFM and STM have certain commonalities, they also have some substantial differences. Read this article to find out more about AFM and STM and how they are different from each other. What is AFM? AFM works on the interaction forces between the tip and the sample ... Read More

Introduction The positron is regarded as the positive electron where it is generally charged positively to the subatomic particles. Additionally, the particles that are charged can be equal to the subatomic magnitude of the electrons that are charged to create an antiparticle of a negative electron. Information About Electron, Neutron, Nucleon, And Proton The wreck of a positron which contains low energy and an electron that also contains low energy makes the consequence in the appearance of two or more gamma rays photons. This procedure is comprehended as the electron-positron annihilation. Electrons, protons, and neutrons are comprehended as ... Read More
