The variation in energy levels between neighboring molecules. Transfer Integral: How well the -orbitals of adjacent molecules overlap.

The weak intermolecular forces lead to a high degree of structural and energetic disorder, especially in thin films. Instead of the neat, periodic energy bands found in a silicon crystal, the electronic states in an organic semiconductor are more accurately represented by a . This distribution is broadened by static disorder—variations in molecular spacing and orientation—as well as dynamic disorder from thermal molecular vibrations. This "Gaussian landscape" is the stage upon which the key physical processes of charge transport and photophysics play out. physics of organic semiconductors pdf

When an organic semiconductor absorbs a photon, an electron jumps from the HOMO to the LUMO. Instead of creating a free electron and a free hole, the Coulombic attraction binds them together into a neutral quasipoint called an . The variation in energy levels between neighboring molecules

-conjugated systems . Unlike traditional inorganic semiconductors (like Silicon) that rely on covalent bonds, organic semiconductors are held together by weaker . Core Physical Principles Physics of Organic Semiconductors | Wiley Online Books Instead of the neat, periodic energy bands found

In the world of materials science, the term "semiconductor" usually brings to mind rigid silicon wafers and inorganic crystals. However, a revolutionary class of materials——has redefined what electronics can look like. By combining the electrical properties of semiconductors with the mechanical flexibility of plastics, these materials have paved the way for OLED screens, flexible solar cells, and wearable sensors.
