[2Cp09] Functional Atomic Composite: A New Prospect of MICAtronics

*Ying-Hao Chu¹ (1. National Tsing Hua University)

Muscovite mica, a 2D layered oxide, is the most significant available natural and synthetic 2D layered single crystal. Due to its 2D feature, an atomically smooth surface can be obtained for van der Waals heteroepitaxy, and superior mechanical flexibility can be utilized for bending conditions. Taking the nature of the 2D layered structure of muscovite, a van der Waals gap of 0.3 nm exists between layers, which can be viewed as a 2D cavity. The idea of this study is to use this 2D cavity to create a new material form by inserting chemical species, primarily focusing on transition metal ions. Then, a heat treatment is implemented to transfer transition metal ions into crystalline form. These newly formed systems with muscovite can be viewed as an atomic composite due to the atomic layer stacking of the heterostructure.
