What is Nanostructure Analysis?
Nanostructure analysis is the process of examining materials and devices at the nanoscale, typically involving structures with dimensions less than 100 nanometers. This analysis is crucial in the field of
nanotechnology as it helps understand the properties, behavior, and potential applications of nanoscale materials.
-
Transmission Electron Microscopy (TEM): TEM provides high-resolution images of nanostructures by transmitting a beam of electrons through a thin specimen.
-
Scanning Electron Microscopy (SEM): SEM scans the surface of a specimen with a focused beam of electrons to create detailed images of surface topography and composition.
-
Atomic Force Microscopy (AFM): AFM uses a cantilever with a sharp tip to scan the surface of a sample, providing topographical data at the nanoscale.
-
X-ray Diffraction (XRD): XRD analyzes the crystalline structure of materials by measuring the diffraction patterns of X-rays passing through the sample.
-
Raman Spectroscopy: This technique uses the scattering of monochromatic light to provide information about molecular vibrations, which can be used to identify molecular composition and structure.
-
Resolution: Achieving high resolution to clearly observe nanoscale features can be difficult.
-
Sample Preparation: Preparing samples without altering their nanostructure can be challenging, especially for delicate materials.
