In semiconductors, an absorbed photon can create a bound electron-hole pair called an exciton, which dominates the optical spectrum at low temperatures.
An increase in electrical conductivity caused by light absorption (used in light sensors). Optical Properties of Solids
The optical properties of solids describe how electromagnetic radiation—ranging from infrared to ultraviolet—interacts with condensed matter. This field is essential for developing technologies like lasers, solar cells, and fiber optics. In semiconductors, an absorbed photon can create a
When light strikes a solid, three primary phenomena occur: , absorption , and transmission . The balance between these depends on the material's internal electronic structure. Licensed by Google This field is essential for developing technologies like
At its core, the response of a solid to light is determined by its ( ) and its dielectric function (
To quantify these interactions, scientists use two main parameters: Refractive Index (
