ABSTRACT: With aim to increase set of modern commercial optoelectronic devices we investigate
the optical properties of new triple semiconductor-organics-semiconductor
nanostructure having two semiconductor layers with organic layer
between. This will be development to majority of modern publications with
investigations of only double hybrid nanostructures with one contacting semiconductor
layer and one organic layer. It is supposed that the energy of exciton
in the first layer is larger than the energy of exciton in organic layer and
that the energy of exciton in organic layer is larger in comparison with energy
of exciton in second semiconductor layer. It was shown that installation of
organics leads to some frequencies at different parameters or to reflection increasing
and transmission decrease or to reverted dependence. New recurrent
method of inverted calculation for fields is proposed and using this method
the frequency dependences of optical characteristics have been calculated. The
role of second semiconductor layer in considered triple structure has been estimated.
