SHG is a powerful technique in nanotechnology for several reasons:
Non-destructive probing: SHG can be used to investigate the structural and electronic properties of materials without damaging them. Surface sensitivity: SHG is inherently sensitive to surfaces and interfaces, making it ideal for studying thin films, nanoparticles, and other nanostructures. High spatial resolution: When combined with microscopy techniques, SHG can provide high-resolution images of nanoscale features.
