摘      要：Crystallization,while a common process in nature,remains one of the most mysterious *** its physical mechanisms is essential for obtaining high-quality ***,crystals grown by thermal evaporation or sublimation nucleate the substrate facing the evaporation ***,a novel vapor micro-turbulence mass transport mechanism in the growth process of ultrathin BiOCl single crystals has been *** this mechanism,the precursor vapor bypasses the solid substrate,forming micro-turbulent vaporizing flows to nucleate on the surface of the substrate facing away from the evaporation *** nucleation kinetics,fast shear flows are known to cause secondary nucleation,increasing nucleation quantity while decreasing the final size of the ***,the nucleation and growth process of BiOCl crystals are controlled by adjusting the micro-turbulence intensity to reduce shear flow energy and dilate phase distribution,resulting in BiOCl crystals with uniform distribution and regular *** structural and morphological characterization confirms the high crystallization quality of the obtained crystals,and the performance of the constructed solar-blind photodetectors is comparable to that of similar *** findings contribute to a deeper understanding of vapor mass transport and crystal growth techniques and may be useful for applications related to metal oxide crystals.
