  We report piezoelectric response in liquid phase exfoliated MoS2 nanosheets
with desired structure and morphology. The piezoelectric effect in liquid phase
exfoliated few layers of MoS2 flakes is interesting as it may allow the
scalable fabrication of electronic devices such as self-powered electronics,
piezoelectric transformers, antennas and more. The piezo force microscopy (PFM)
measurements were used to quantify the amplitude and phase loop, which shows
strong piezoelectric coefficient. Herein, the piezoelectric response in few
layers of MoS2 is attributed to the defects formed in it during the synthesis
procedure. The presence of defects is confirmed by XPS analysis
