Two-dimensional materials have attracted great attention for their applications in energy related researches. In this platform, we would like investigate various 2D materials ranged from graphene, TMDs and atomic oxides for their potential applications in energy. Most importantly, the fundamental mechanisms of these 2D materials will be explored using the state-of –the-art analytics techniques, based on the previous foundation established under the support of TCECM project. In 2D organic-inorganic perovskites, we would like to explore novel optical and electronic properties of this emerging material together with its applications in photovoltaic and optoelectronic applications.二維材料原子層二維有機無機鈣鈦礦Two-dimensional materials,atomic layer2D perovskite「台大核心研究群」計畫【新穎二維原子層材料之成長與開發】
