Toward Quantitative Prediction of Charge Mobility in Organic Semiconductors: Tunneling Enabled Hopping Model

A tunneling‐enabled hopping mechanism is proposed, providing a pratical tool to quantitatively assess charge mobility in organic semiconductors. The paradoxical phenomena in TIPS‐pentacene is well explained in that the optical probe indicates localized charges while transport measurements show bands...

Zusammenfassung:A tunneling‐enabled hopping mechanism is proposed, providing a pratical tool to quantitatively assess charge mobility in organic semiconductors. The paradoxical phenomena in TIPS‐pentacene is well explained in that the optical probe indicates localized charges while transport measurements show bands of charge.
