マルチ層配列：分子層内外の電子-格子自由度制御に基づく超薄膜機能の新展開

Overview

With the explosive progress of the IoT society, the exploration of electronic materials is shifting from three-dimensional bulk crystals to two-dimensional (2D) systems. Ultrathin films with nanometer-scale thickness are the most promising 2D material form for the development of exotic quantum phenomena. Here, we pursue low-dimensional electronic properties emerging at the end of 2D downscaling of various electronic phases, based on charge-transfer (CT) complexes, in which multiple electronic phases compete and coexist due to the lattice, charge, and spin degrees of freedom. We aim to emerge and control unique electronic properties by achieving the ultrathin films of “Multiply Programmed Layers” with the intra-/interlayer molecular arrangements and forming a variety of band structures with electronic coupling based on molecular orbital hybridization.
