Machine-Learning Force Fields Reveal Shallow Electronic States on Dynamic Halide Perovskite Surfaces
Previous studies indicated that defects in halide perovskites can generate shallow electronic states, which are crucial for their performance in devices. However, how shallow states persist amid prono...

Why are halide perovskites so efficient? Part of their great performance is in their nature of electronic surface states. ☀️ In our preprint, we reveal the atomistic origins of benign surface states using machine-learning force fields 🤖. Find out more in our recent preprint: arxiv.org/abs/2502.19772
