Analysis
This paper presents a unified framework to understand and predict epitaxial growth, particularly in van der Waals systems. It addresses the discrepancy between the expected rotation-free growth and observed locked orientations. The introduction of predictive indices (I_pre and I_lock) allows for quantifying the energetic requirements for locked epitaxy, offering a significant advancement in understanding and controlling heterostructure growth.
Key Takeaways
