Pdf Fixed — Physics Of Organic Semiconductors

The transition from rigid, high-heat processing to "soft" electronics represents one of the most exciting frontiers in condensed matter physics today.

—quasiparticles formed by a charge and its associated lattice deformation. Transport occurs via a "hopping" mechanism between localized molecular states. Exciton Dynamics physics of organic semiconductors pdf

The unique physics of these materials allows for devices that silicon simply cannot match: The transition from rigid, high-heat processing to "soft"

: Unlike covalently bonded inorganic semiconductors (like Silicon), organic solids are held together by weak van der Waals interactions . This leads to localized electronic wavefunctions and lower melting points. Exciton Dynamics The unique physics of these materials

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.
