| Outline of Final Research Achievements |
Metal-halide perovskite-type semiconductors are used in light-absorbing layers of the perovskite solar cells which have been invented by Japanese researchers. We have investigated fabrication of methylammnonium lead halide heterostructures bearing potential applications to light-emitting devises in mind. We have succeeded in fabricating polycrystalline heterostructures by using vacuum evaporation technique for the first time. Moreover, we have also succeeded in the first demonstration of hetero-epitaxial thin-film formation on single-crystal lead-bromide perovskite substrates. In addition, we have studied a novel phenomenon, photo-induced phase separation of semiconductor alloys, which will hinder band engineering of the perovskite-type semiconductors.
