Thin-film preparation refers to the techniques and processes used to create very thin layers of material, typically less than a few micrometers in thickness, on a substrate. This process is essential in many applications, especially in optics and electronics, as it allows for the manipulation of light and electronic properties of materials. In the context of terahertz spectroscopy of biomolecules and tissues, thin films can be crucial for creating samples that accurately represent biological structures and their interactions with terahertz radiation.
