What Techniques are Used to Achieve Better Resolution?
Several advanced techniques are employed to achieve better resolution in nanotechnology:
Scanning Electron Microscopy (SEM): This technique uses focused beams of electrons to create high-resolution images of surfaces. Transmission Electron Microscopy (TEM): TEM provides even higher resolution by transmitting electrons through a thin sample, offering insights into the internal structure of materials. Atomic Force Microscopy (AFM): AFM uses a tiny mechanical probe to scan the surface of a sample, providing topographical maps at the nanoscale. Scanning Tunneling Microscopy (STM): STM leverages quantum tunneling to achieve atomic-level resolution, allowing for the imaging and manipulation of individual atoms.
