Organic semiconductors have gained significant attention in recent years due to their potential applications in flexible electronics, optoelectronics, and photovoltaics. These materials offer a promising alternative to traditional inorganic semiconductors, with advantages such as flexibility, low-cost processing, and environmental sustainability. In this post, we'll explore the physics underlying organic semiconductors, discussing their unique properties, challenges, and opportunities.
The power of this book, and others like it, lies in its systematic approach to the subject. It is typically divided into four major sections, each tackling a cornerstone of the field. This structure is an excellent guide to the essential topics you need to understand. In place of the valence and conduction bands
-electrons form molecular orbitals. The highest occupied molecular orbital (HOMO) corresponds to the valence band in inorganic semiconductors, and the lowest unoccupied molecular orbital (LUMO) corresponds to the conduction band. The energy difference between the LUMO and HOMO (
