Abstract(in English) | For a development of photonic devices utilizing InN properties, it is necessary to control (1) the p-type conductivity in InN and In-rich InGaN, and (2) the structural perfection of quantum well structures. A new development of InN-based novel photonic detectors is proposed, based on our achievements of the p-type conductive control and the 1-monolayer-thick InN quantum wells. Especially, the InN/InGaN/GaN asymmetric quantum well structures, which have been recently investigated, are expected for application not only to emitters suppressing QCSE, but also to third generation ultrahigh-efficiency solar cells, and to infrared photo-detectors. In this article, a design concept and a feature of the photonic detectors are presented. When the InGaN tandem solar cells including 1ML-InN QWs as a photo-sensitizer are composed, theoretical evaluation shows that the maximum conversion efficiency reaches 56% for the 6 tandem structure (further 65% under 250 suns). |
