Understanding the physics of these materials requires a shift from traditional band theory to models that account for molecular disorder and strong electron-phonon coupling. Fundamental Concepts of Organic Semiconductors
The book has since become a standard reference, with contributions from 18 international research groups across the US, Japan, and Europe, consolidating decades of research into a single, authoritative volume. Its second edition, published in 2012, is "completely new revised," incorporating the significant developments and deeper scientific understanding that had occurred over the preceding years.
The physics of organic semiconductors is a rich and complex field, with many challenges and opportunities. By understanding the underlying physics, researchers and engineers can design and develop new materials and devices with improved performance and functionality.
between organic and inorganic semiconductor physics. Let me know which area you'd like to explore further! Introduction to the physics of organic semiconductors
OFETs serve as the switching elements in flexible displays and circuits. They utilize a three-terminal architecture (Source, Drain, Gate). Applying a voltage to the insulated gate modulates the charge density at the organic-dielectric interface, drastically altering the channel conductivity and controlling the current flow between the source and drain. 5. Summary Table: Organic vs. Inorganic Semiconductors Organic Semiconductors Inorganic Semiconductors (e.g., Silicon) Weak Intermolecular Van der Waals Strong Covalent / Ionic Bonds Structure Amorphous to Polycrystalline Highly Crystalline Primary Excited State Tightly Bound Frenkel Exciton ( Free Carriers / Wannier Exciton ( Transport Mechanism Temperature-assisted hopping Delocalized band transport Carrier Mobility ( ) 10-510 to the negative 5 power 10210 squared Temperature Effect Mobility increases with temperature Mobility decreases with temperature Processing Low-cost solution processing / vacuum printing High-temperature cleanroom processing
For anyone seeking a comprehensive PDF on the physics of organic semiconductors, the most highly regarded resource is the book titled edited by Wolfgang Brütting and Chihaya Adachi. First released in 2005, this text was groundbreaking as it filled a significant gap in scientific literature, providing a much-needed overview of a field that was, at the time, rapidly emerging from its infancy.
for silicon). Because of weak electrostatic screening, the photo-generated electron and hole experience a strong Coulombic attraction. Frenkel Excitons
The Physics of Organic Semiconductors: Principles, Mechanisms, and Applications
: Use donor-acceptor interfaces to separate tightly bound excitons into free charges.
When an organic semiconductor absorbs a photon, it doesn't immediately create a free electron and hole. Instead, it creates an —a bound electron-hole pair held together by strong electrostatic (Coulombic) attraction.
