Recently, two-dimensional transition metal dichalcogenides have intrigued much attention due to their promising applications in optoelectronics. The electrostatic property investigation of WSe{sub 2} nanostructures is essential for device application. Here, the interlayer screening effects of WSe{sub 2} nanoplates with different thicknesses were investigated by measuring surface potential employing Kelvin probe force microscopy. Simultaneously, charges can be injected into WSe{sub 2} nanoplate by means of conducting atomic force microscopy to tune the electrostatic properties of WSe{sub 2} nanostructures. Our experimental results have some important implications for improving performance of WSe{sub 2}-based optoelectronic devices through interface or surface engineering.
