    Comparison of Dislocation Loop Formation Resistance in Nanocrystalline and Coarse-Grained Refractory High Entropy Alloys

    In nanocrystalline high entropy alloys (HEAs), the difference in chemistry and the density of interfaces play a role in the microstructure evolution, although their relative importance is not well understood. ...

    Study of scalable IBS nanopatterning mechanisms for III-V semiconductors using in-situ surface characterization

    Ion-beam sputtering (IBS) has been studied as a means for scalable, mask-less nanopatterning of surfaces. Patterning at the nanoscale has been achieved for numerous types of materials including: semiconductors...
