TITLE:
Derivation of Oscillatory Dynamics of Silicon Structure Under Indium Adsorption

ABSTRACT：
Indium adsorption on silicon (Si) (111) surface, a model for thin film growth, is temperature-dependent and crucial for semiconductor device engineering. At low temperatures (290℃), Si showed 4×1 and √3×√3 structures with chaotic fluctuations, complicating first-principles calculations. We used machine learning to derive the quantitative equations, revealing an oscillator relationship.
