Key Points

Investigate how sulfuration reaction rates and sulfur concentration gradients affect the morphological evolution and growth patterns of MoS2 during chemical vapor deposition.
Synthesized molybdenum disulfide (MoS2) via chemical vapor deposition within an underdeveloped laminar flow boundary layer.
Evaluated the impact of surface-chemistry-limited conditions and sulfur vapor concentration gradients on crystal morphology.
Obtained space-uniform MoS2 growth when deposition was limited by surface chemistry inside the boundary layer.
Identified that the crystal growth pattern is directly governed by the local growth rate.

Implication

Experimental analysis demonstrates surface-chemistry-limited MoS2 growth in laminar flow boundary layers, indicating crystal growth patterns are governed by reaction rates.

Abstract

Space-uniform MoS 2 limited by surface chemistry can grow through CVD within an underdeveloped laminar flow boundary layer, with crystal growth patterns being governed by the growth rate.
