Free(wannier-mott)
Radius >> a(exciton Bohr radius)
Small binding energy :~ 0.01 eV
Delocalized states
Move freely through crystal
(semiconductors)
Tighthly-bound(Frenkel)
Radius ~ a(exciton Bohr radius)
large binding energy : 0.1 -1.0 eV
localized on one lattice site
Moving by hopping
(insulators and molecules)
Eadd = △E + Ec
Ec = e2/C
C = 2πεεod
(depend on geometry)
ε:permitivity
