You can copy and paste this guide into a document editor (like Word or Google Docs) and save it as a PDF for your personal use. This guide covers the fundamental concepts typically found in standard textbooks (such as those by Anna Köhler, Heinz Bässler, or M. Pope). The physics of organic semiconductors is a complex
Because these materials are often disordered or amorphous, charge transport is fundamentally different from the crystal-lattice flow in inorganic semiconductors.
Organic semiconductors have gained significant attention in recent years due to their potential applications in various electronic devices, such as organic light-emitting diodes (OLEDs), organic photovoltaic cells (OPVs), and organic field-effect transistors (OFETs). The physics of organic semiconductors is a complex and multidisciplinary field that involves the study of the electronic and optical properties of organic materials. In this article, we will provide a comprehensive review of the physics of organic semiconductors, including their electronic structure, charge transport, and optical properties.
In place of the valence and conduction bands found in inorganic crystals, organic semiconductors utilize molecular orbitals:
