1. of, relating to, or involving an exciton (a bound state of an electron and a hole in a semiconductor or insulator)
Usage: technical; physics

Examples

• The excitonic properties of the semiconductor were studied using spectroscopy.
• Excitonic effects become significant in thin films and nanostructures.
• The researchers measured the excitonic binding energy of the material.
• Excitonic transitions are important for understanding light absorption in organic semiconductors.
• The excitonic state decays rapidly at room temperature in this compound.
