(MDPI, 2023): This paper provides a comparative analysis of transport mechanisms, specifically detailing the "hopping" mechanism typical in disordered organic materials. Study of Organic Semiconductors for Device Applications

For a quick : Start with the review "Electronic Processes in Organic Semiconductors" by Köhler & Bässler (Wiley, 2015) – also available in PDF form through institutional access. physics of organic semiconductors pdf

1. Electronic Structure: From Molecular Orbitals to Energy Bands

Understanding these physical parameters has enabled the development of highly efficient commercial organic electronic architectures. Organic Light-Emitting Diodes (OLEDs) Study of Organic Semiconductors for Device Applications For

Localization on a single molecule or monomer unit (small radius).

: Instead of the valence and conduction bands found in inorganic crystals, organic semiconductors use the Highest Occupied Molecular Orbital (HOMO) Lowest Unoccupied Molecular Orbital (LUMO) . The energy gap typically ranges from 1.5 to 3 eV. Bonding Forces physics of organic semiconductors pdf

: Instead of the "conduction" and "valence" bands found in silicon, organic physics focuses on: HOMO (Highest Occupied Molecular Orbital) LUMO (Lowest Unoccupied Molecular Orbital) Energy Gap : Similar to the

Excitons exist in two primary spin configurations based on quantum mechanics: Total spin

Because of the weak intermolecular interactions, charges tend to become localized on a single molecule or monomer unit. Transport happens via , a process where charge carriers "jump" from one molecule to another, assisted by phonons (molecular vibrations). Marcus Theory

. Carriers jump between localized states because the materials are often disordered or amorphous. Light absorption in these materials creates
