What Techniques are Used for Enhanced Visualization?
Several advanced techniques are employed for enhanced visualization in nanotechnology:
1. Scanning Electron Microscopy (SEM): Uses electron beams to create high-resolution images of surfaces. SEM is widely used for material characterization.
2. Transmission Electron Microscopy (TEM): Provides even higher resolution images by transmitting electrons through a thin sample. TEM is useful for examining the internal structure of nanomaterials.
3. Atomic Force Microscopy (AFM): Uses a cantilever with a sharp tip to scan the surface. AFM can measure topography, mechanical properties, and other surface characteristics at the nanoscale.
4. Scanning Tunneling Microscopy (STM): Utilizes quantum tunneling to image surfaces at the atomic level. STM is highly effective for studying conductive materials.
5. X-ray Diffraction (XRD): Used to determine the crystalline structure of nanomaterials. XRD provides information about the arrangement of atoms within a sample.
