この成果は、量子ドット超格子における多重励起子生成など、新たな光物性の解明に貢献するだけでなく、他のナノマテリアルを利用した次世代デバイスの実現にも寄与すると期待できます。","subitem_description_language":"ja","subitem_description_type":"Abstract"},{"subitem_description":"In quantum dot superlattices, wherein quantum dots are periodically arranged, electronic states between adjacent quantum dots are coupled by quantum resonance, which arises from the short-range electronic coupling of wave functions, and thus the formation of minibands is expected. Quantum dot superlattices have the potential to be key materials for new optoelectronic devices, such as highly efficient solar cells and photodetectors. Herein, we report the fabrication of CdTe quantum dot superlattices via the layer-by-layer assembly of positively charged polyelectrolytes and negatively charged CdTe quantum dots. We can thus control the dimension of the quantum resonance by independently changing the distances between quantum dots in the stacking (out-of-plane) and in-plane directions. Furthermore, we experimentally verify the miniband formation by measuring the excitation energy dependence of the photoluminescence spectra and detection energy dependence of the photoluminescence excitation spectra.","subitem_description_language":"en","subitem_description_type":"Abstract"},{"subitem_description":"The authors acknowledge Thermo Fisher Co. for the STEM measurements.
