The electronic states in organic semiconductors can be described using the molecular orbital theory, which takes into account the overlap of atomic orbitals to form molecular orbitals. The highest occupied molecular orbital (HOMO) and the lowest unoccupied molecular orbital (LUMO) are the frontier orbitals that play a crucial role in determining the electronic properties of organic semiconductors.

The electronic structure of organic semiconductors is characterized by a filled valence band and an empty conduction band, similar to inorganic semiconductors. However, the electronic states in organic semiconductors are often described using a molecular orbital (MO) approach, rather than the band structure approach used for inorganic semiconductors. In the MO approach, the electronic states are described in terms of the molecular orbitals of individual molecules or polymer chains. physics of organic semiconductors pdf
