Enhanced Nonlinear Optical Response of Rectangular MoS<sub>2</sub> and MoS<sub>2</sub>/TiO<sub>2</sub> in Dispersion and Film
The
nonlinear response of the two-dimensional materials could be measured
by the spatial self-phase modulation (SSPM) and Z scan. Most of these
materials are irregular shapes. In this paper, we studied the nonlinear
optical properties of rectangular layered MoS<sub>2</sub> and the
corresponding MoS<sub>2</sub>/TiO<sub>2</sub> composite in dispersion
and the film, respectively. For dispersion measured by SSPM, the nonlinear
refraction index of rectangular layered MoS<sub>2</sub> dispersion
is larger than that of the MoS<sub>2</sub>/TiO<sub>2</sub> composite
dispersion. For film measured by Z scan, the nonlinear refractive
index of the MoS<sub>2</sub>/TiO<sub>2</sub> composite thin film is
larger than that of the rectangular layered MoS<sub>2</sub> thin film.
This research confirms the possibility of the nonlocal electron coherence
established among the alignment in SSPM and provides two different
paths for the enhancement of the nonlinear optical properties of MoS<sub>2</sub>
