display technology– sourced from Russia and Canada– Part of the indium tin oxide layers (ITO)– primary conductor used on glass substrates
because of “wetting” properties

recombination of electrons and holes– Action from an atom in
an excited state undergoes a transition to ground
– releases a photon
• Primary parts are– hole donor– electron donor– emissive layer

D• Advantages of organic semiconductors
– molecules are held together by weak van der waals forces
– carrier mobilities are low• typically less than 1cm2/v-s
– high fluorescence efficiencies– epitaxy is not required– properties can be tailored with Types of
Materials– *can be fabricated on large substrates
