The story of organic semiconductors is a transition from rigid, inorganic crystals like silicon to flexible, carbon-based molecules that behave like electronic materials. Unlike traditional semiconductors, organic ones are made of low-molecular-weight materials or polymers. Their physics is defined by conjugated

Conclusion
From Inorganic to Organic: A Shift in Paradigm
In inorganic semiconductors like silicon, atoms bond covalently into a rigid lattice, forming delocalized energy bands. Electrons occupy valence and conduction bands separated by a bandgap. In organic semiconductors, the physics is quite different. They consist of conjugated molecules or polymers—long chains of carbon atoms with alternating single and double bonds. This π-conjugation allows electrons to delocalize along the molecule, creating molecular orbitals: the highest occupied molecular orbital (HOMO) and the lowest unoccupied molecular orbital (LUMO). The HOMO–LUMO gap is the organic analog of the bandgap. The header tags used in this article are:
