Synthesis of ultrathin Cr23C6 MXene

Abstract

Two-dimensional (2D) materials have intensely attracted attention due to their excellent physical and mechanical properties such as high mobility, high on/off ratio, and flexibility. The changing of band gap from bulk to monolayer, makes them trivial for next generation applications such as field-effect transistors, flexible devices, spintronic devices, and electronic devices. This report will cover synthesis and characterization of ultrathin Chromium Carbide (Cr23C6). In this project, Cr23C6 was synthesized by using chemical vapor deposition technique. The impacts of precursors selection, ramping time, holding temperature, holding time, and gas flow rate on the sample were examined and analyzed by using different type instruments such as scanning electron microscope (SEM), Raman Spectroscope, atomic force microscope (AFM), and optical microscope.
