What is AFM Atomic force microscope (AFM) is a kind of scanning probe microscope (SPM) that came out in the early 1980s. In 1986, Dr. Binning won the Nobel Prize in Physics for his invention of the scanning probe microscope. The magnification of this microscope far exceeds any previous microscope: the magnification of optical microscopes generally does not exceed 1000 times; the magnification...

What is Graphene? Graphene is a two-dimensional carbon nanomaterial composed of carbon atoms in a hexagonal honeycomb lattice with special hybrid orbitals. It has excellent optical, electrical, and mechanical properties. Materials with light weight, strongest toughness, best light transmittance, and best electrical and thermal conductivity have important application prospects in materials...
