摘要：

The photoconductivity of a thin semiconductor film is enhanced by depositing a photonic crystal layer on its backside. As shown in the figure, simulations indicate that the enhanced photoconductivity arises from the resonant modes in the filmphotonic-crystal constructs and exceeds the enhancement obtained by depositing a perfect mirror onto the film.
