title: Dynamic self-diffraction in MoS(2) nanoflake solutions.
abstract: We observe dynamic self-diffraction in MoS(2) supernatant solutions with laser for the first time, and conduct dynamic data simulation and analysis. Observation results indicate that self-diffraction can be divided in three stages: in the first stage, laser changes from Gauss beam to symmetric diffraction rings because of the force from laser. In the second stage, diffraction rings become asymmetric vertically because of gravity. In the third stage, diffraction rings become asymmetric horizontally, as a result of fine structure of laser. We obtain the dynamic distribution of MoS(2) nanoflake in solution under the effect of laser by dynamic diffraction image simulation.
