Electron-phonon scattering is often the primary mechanism limiting electron mobility in semiconductors. Thus, changing phonon properties can provide a way to control conductivity. Recently, there has been a growing interest in exploring the use of the quantum nature of light as an alternative approach. In this method, the material properties are modulated by tuning its interaction with the vacuum state of the electromagnetic field.
