Because of its excellent energy resolution ( ~ 170 eV ) , a SSD has been used
recently for energy dispersive fluorescence studies , determining the elemental
constituents of a specimen by analyzing the energy of photons emitted from the ...

The excitonic bandgap Egx = Eg – Ex is therefore easily accessible , while the
bandgap Eg requires the knowledge of the free exciton binding energy Ex , which
is at present very difficult to measure by any method ( Elliot , 1957 ; Dean and ...
