In a perfect crystal, momentum (k) is a good quantum number. In amorphous or polycrystalline organic thin films, momentum is not conserved. Instead of broad bands, we have a Gaussian distribution of density of states (DOS). The most common model used is the , pioneered by Bässler. It describes transport in terms of energetic disorder (σ) and positional disorder.

Electronic Processes in Organic Semiconductors: An Introduction physics of organic semiconductors pdf

Organic semiconductors are carbon-based materials that exhibit semiconducting properties, meaning that their electrical conductivity lies between that of insulators and conductors. Unlike inorganic semiconductors, such as silicon, organic semiconductors are composed of molecules or polymers that are held together by weak intermolecular forces, such as van der Waals interactions and hydrogen bonding. This unique molecular structure gives rise to distinct physical properties that are different from those of inorganic semiconductors. In a perfect crystal, momentum (k) is a good quantum number
