Controllable growth of transition metal dichalcogenide multilayer flakes with kirigami structures

Author affiliations

Abstract

Two-dimensional (2D) transition metal dichalcogenides (TMDCs) exhibit interesting electronic and optical properties depending on their complex layer stacking and unique architectures. Here, we develop a high-efficiency and low-cost chemical vapor deposition technique to controllably grow 2D MoSe2 flakes with kirigami structures. Optical microscopy, atomic force microscopy, scanning electron microscopy, X-ray photoelectron spectroscopy and transmission electron microscopy were used to characterize the kirigami architectures. Similar kirigami structures can also be extended to WSe2 flakes. This work expands the chemical toolbox for design and fabrication of TMDCs and offers new opportunities for engineering 2D materials with unique three-dimensional architectures and complex layer stacking to develop novel electronic devices and catalysts.
