How is Electromagnetic Radiation Utilized in Nanotechnology?
Electromagnetic radiation is utilized in numerous ways in nanotechnology:
Spectroscopy: Techniques like Raman spectroscopy and UV-Vis spectroscopy rely on electromagnetic radiation to investigate the properties of nanomaterials. Imaging: Methods such as scanning electron microscopy (SEM) and transmission electron microscopy (TEM) use electron beams, a form of electromagnetic radiation, to visualize nanoscale structures. Photolithography: This process uses ultraviolet light to etch detailed patterns onto semiconductor materials, essential for nanoelectronics. Nanophotonics: The study and application of light at the nanoscale, enabling the development of new types of lasers, sensors, and communication devices.
