I major in physics .and now I begain to study about the organic
electroluminisence diodes .
But I don't know much about the LUMO and HUMO,what's the differences
between inorganic diodes'energy bands and the LUMO,HUMO?
the LUMO and HUMO indicates what? what can we get from LUMO and HUMO ?
Anyone with info will be appreciated ! thankyou
The best I can figure, the emission of these devices depends on
molecular energy bands, as opposed to the more simple atomic energy
bands in semiconductor devices. 'HOMO', the Highest Occupied Molecular
Orbital, and the 'LUMO', Lowest Unoccupied Molecular Orbital, would seem
to set the energy gap.
