Semiconductor in which mobile charge carriers are generated solely by thermal excitation of electrons.
Notes:
- Intrinsic semiconductor is free of dopants, so that it has no energy states in the bandgap.
- Pure conjugated polymers such as poly(ethene-1,2-diyl) or poly(pyrrole-2,5-diyl) and other polymers with delocalized valence electrons such as polysilanes are examples of intrinsic semiconductors.
