Monolayer MoS2 With Ultrahigh Piezoelectricity: From ALD Dose Control to Device Performance
Advanced Science, EarlyView.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 ...
