摘要
We investigate terahertz radiation （T-rays） from a pentacene organic diode at room temperature. The quantum chemistry calculation for frequency-related Huang Rhys factor of pentacene is also carried out. The results demonstrate that the T-rays can come from a bending vibration of pentacene skeleton after the energy of pentacene exeiton transferring to the vibrational excited state via electron-phonon coupling. Frequency and natural bond orbital analytics of pentacene and its derivatives are performed in order to explain the result and develop new materials to get higher emission. This work provides a new way to produce T-rays with a simDle device at room temperature.
