Two-Dimensional Layer of Molybdenum Disulfide

Caption

Calculations by Rice University scientists show that a two-dimensional layer of molybdenum disulfide can become superplastic by changing its environmental conditions. In an atmosphere with sulfur and under the right temperature and pressure, the energy barrier is lowered, allowing dislocations along the grain boundaries to shift and changing the material's properties. S2 refers to a disulfur molecule; VS2 is a two-sulfur-atom vacancy.
