Atomistic Kinetics of Dislocation-Mediated Grain Growth in Monolayer MoS₂. [PDF]

Adv Sci (Weinh)
Atomic‐resolution in‐situ heating microscopy directly visualizes dislocation‐mediated grain boundary migration and grain growth in monolayer MoS2. Mobile grain boundaries migrate through collective motion of Mo 5|7 dislocations, whereas S 5|7 defects remain largely immobile.

Monolayer MoS₂ With Ultrahigh Piezoelectricity: From ALD Dose Control to Device Performance. [PDF]

Adv Sci (Weinh)
This study demonstrates that controlling precursor dosages in atomic layer deposition (ALD) serves to regulate ultrathin oxide quality, which in turn determines sulfurization behavior and MoS2 monolayer continuity. The resulting continuous, low‐defect monolayers enable improved piezoelectric performance and support a flexible slippage sensor, linking ...
