ORGANIC SUPERLATTICE OPTICAL RESPONSE DEVICE

摘要

PURPOSE:To provide an organic superlattice optical response device which has a large degree of freedom of material selection and which can increase a conversion efficiency and obtain sufficient sensitivity. CONSTITUTION:An organic superlattice optical response device is prepared by piling up a layer 2 on a layer 1 of organic materials of approximately the same band gap having a different electron affinity (ionized potential). Since this construction forms an electron quantum well and a hole quantum well in two separate phases, an electron and a hole drop into respective wells. Consequently, high sensitivity as an optical response device such as photosensor can be obtained.
