FAQ

What is the Excitation Energy?
Excitation Energy is the energy required to excite an electron from the valence band into the conduction band. Excitation Energy is usually measured using the Electron-Volt for Energy. Note that the value of Excitation Energy is always negative.
Can the Excitation Energy be negative?
Yes, the Excitation Energy, measured in Energy can be negative.
What unit is used to measure Excitation Energy?
Excitation Energy is usually measured using the Electron-Volt[eV] for Energy. Joule[eV], Kilojoule[eV], Gigajoule[eV] are the few other units in which Excitation Energy can be measured.
