吸附原子在二維材料上的遷移行為是基礎科學中重要的資訊。我們嘗試用化學氣相沉積法製備銦吸附原子於單層二硫化鎢的系統,並且利用掃瞄式穿透電子顯微鏡觀察銦吸附原子的遷移行為並進行分析。我們發現在 非晶碳較少的區域,銦原子的遷移行為與理論計算的結果一致;然而非晶碳較多的區域其遷移行為則與理論計算結果稍微不同。
Adatoms migration on 2d material is important for fundamental science. In this thesis, first, we prepare our system - Indium adatoms on monolayer tungsten disulfide by the method of CVD. Then, by taking advantage of the STEM technique, we detect the migration of adatoms by in-situ ADF-STEM images. Experiment results show the same trend as theoretical calculation in clean regions, while slightly different in amorphous carbon-rich regions.
