Abstract: (3227 Views)
In this paper, the nonlinear optical properties of two-dimensional MoS2 nanostructure are investigated using the Z-scan method by continuous wave lasers with 12 and 55 mW at 532 nm. The properties of the size and sign of the nonlinear refractive index and the nonlinear absorption coefficient are calculated using the Z-scan technique. The corresponding third-order susceptibilities is determined to be as large as 10-7 (esu) under laser excitation. This large third-order optical nonlinearity, makes this structure suitable for application of optoelectronic devices and phototransistors.
