: Electrons and "holes" move by "hopping" between localized states on different molecules, rather than moving through a continuous band. physics of organic semiconductors pdf

The physics of organic semiconductors is a mature yet rapidly evolving field. While silicon will never disappear, the unique mechanical flexibility, solution processability, and tunable optical properties of organics have secured their place in the technological landscape. Free carriers drift to their respective electrodes for

To understand the physics of organic semiconductors, one must look at the hybridization of carbon atoms. Hybridization ( sp2sp squared In a conjugated organic molecule, carbon atoms undergo sp2sp squared hybridization. Each carbon atom forms three localized To understand the physics of organic semiconductors, one
