    Macro-superlubricity in sputtered MoS2-based films by decreasing edge pinning effect

    To date, MoS2 can only be achieved at microscale. Edge pinning effect caused by structure defects is the most obvious barrier to expand the size of structural superlubricity to macroscale. Herein, we plan to pin ...
