= Electroreflectance
{wiki=Electroreflectance}
Electroreflectance is an optical characterization technique used to study the electronic properties of materials, particularly semiconductors and thin films. It involves applying an electric field to a material while measuring the reflectivity of light that is incident on the sample. The change in reflectivity as a function of the applied electric field provides insights into the energy levels, band structure, and other electronic properties of the material.
