The first synthesis is reported of high-entropy two-dimensional layered sheets of carbide MXenes with four transition metals each (TiVNbMoC3 and TiVCrMoC3).
Significance and Impact
This work significantly expands the compositional variety of the MXene family and provides a method of designing 2D materials with tailored and tunable material properties for diverse potential applications.
- Synthesis was confirmed using X-ray diffraction, scanning electron microscopy, scanning transmission electron microscopy, X-ray photoelectron spectroscopy and energy dispersive X-ray spectroscopy.
- The Center for Nanoscale Materials (CNM) high-performance computing Carbon Cluster was used to compute the formation energies and explore the ability to synthesize high-entropy MAX phases.
Work was performed in part at CNM.
About Argonne’s Center for Nanoscale Materials
The Center for Nanoscale Materials is one of the five DOE Nanoscale Science Research Centers, premier national user facilities for interdisciplinary research at the nanoscale supported by the DOE Office of Science. Together the NSRCs comprise a suite of complementary facilities that provide researchers with state-of-the-art capabilities to fabricate, process, characterize and model nanoscale materials, and constitute the largest infrastructure investment of the National Nanotechnology Initiative. The NSRCs are located at DOE’s Argonne, Brookhaven, Lawrence Berkeley, Oak Ridge, Sandia and Los Alamos National Laboratories.
