2604.01233 Superlubric Sliding Between Incommensurate MoS2 Layers Breaks Down at Contact Pressures Above 2.1 GPa: A Phase Transition to Commensurate Locking
We report a systematic investigation of superlubricity with quantitative characterization spanning multiple length scales and operating regimes. Our methodology combines first-principles theoretical analysis, finite-element numerical simulations, and experimental measurements on fabricated samples to establish precise performance boundaries.
