For the potential applications in ferroelectric switching and piezoelectric nano-generator device, the promising ferroelectric properties of two dimensional (2D) layered In2Se3 attracted much attention. In the present study, 2D In2Se3 flakes down to monolayers are grown by chemical vapor deposition (CVD) technique on mica substrate with the structural, optical and ferroelectric properties being studied. The effect of growth parameter (time of growth and Ar flow rate) on the shape and size of the deposited flakes...
