Piezoelectric Electronics
In article number 2201630, Zhigao Hu, Zengfeng Di, and co‐workers demonstrate the synthesis of 2D Mo1−xWxS2 alloy with variable W concentrations. By precisely tuning the fraction of W close to that of Mo, the Mo0.46W0.54S2 alloy has the highest configurational entropy and the best piezoelectric properties among Mo1−xWxS2‐type alloys with different compositions.
Piezoelectricity in 2D transition metal dichalcogenides (TMDs) has attracted considerable interest because of their excellent flexibility and high piezoelectric coefficient compared to conventional piezoelectric bulk materials. However, the ability to regulate the piezoelectric properties is limited because the entropy is constant for certain binary TMDs other than multielement ones. Herein, in order...
