The image depicts a novel precision patterning method using the United States Department of the Air Force emblem on monolayer MoSe2, a two-dimensional material made of atomic layers. Air Force Research Laboratory, or AFRL, researchers from the Materials and Manufacturing Directorate contributed this work to the February 2023 ACS Nano publication “Precision Modification of Monolayer Transition Metal Dichalcogenides via Environmental E‑Beam Patterning.” The publication introduced an innovative process of altering and tailoring the optoelectronic properties of transition metal dichalcogenides, or TMDs. Researchers can control and manipulate the atomic properties of these materials to draw lines, shapes and desired patterns to demonstrate how the material’s thermal and optical properties can be manipulated for sensing and other technologies.
