本プロジェクトでは、透過型電子顕微鏡(TEM)研究に用いる新しい試料担体を作製し、層間インターカレーション機構を顕微鏡で直接観察することを可能にします。このプロジェクトの目的は、層状物質のインターカレーションや脱離に伴う金属イオンや化合物の動的挙動を原子レベルで直接観察・記録することである。同時に、インターカレーションされた化合物の電気的・光学的特性を測定し、インターカレーション物質が与える電荷移動の効果についてより深く理解する。
We investigated the atomic structure of metal chlorides and alkali metals intercalated into bilayer graphene (BLG) using STEM. Our results revealed structural deviations from the original materials; for instance, MoCl5 intercalation resulted in MoCl3 and other MoClx nanostructures. This emphasizes the need for atomic-resolution imaging to accurately ascertain the properties of intercalation compounds (published in ACS Nano).Further, we found that K, Rb, and Cs intercalated into BLG form a hcp bilayer, challenging the expected single-metal-layer intercalation. From this, we proposed a new graphite intercalation model where the surface-near interlayer expands to accommodate a metal bilayer, while central layers retain a single-metal form, detailed in Nature Communications.
