Semiconductors Pdf: Physics Of Organic

: In disordered films, charges "hop" between localized sites. This process is thermally activated and follows a Gaussian distribution of energy states.

The defining physical characteristic of OSCs is the formation of delocalized $\pi$-electron systems. Because these electrons are loosely bound, they can be excited across energy gaps typically ranging from 1.5 to 3 eV, placing OSCs in the visible light spectrum regime. However, unlike the rigid lattice of silicon, OSCs are Van der Waals solids; the weak intermolecular forces lead to localized electronic states and significant structural disorder. physics of organic semiconductors pdf
