First-principles study of hydrogen diffusion in polycrystalline Nickel
Bhanuj Jain, Alaa Olleak, Junyan He +2
Hydrogen embrittlement in metals is strongly governed by hydrogen diffusion and trapping, yet predicting these effects in polycrystalline systems remains challenging. This work int…
Polycrystal plasticity with grain boundary evolution: A numerically efficient dislocation-based diffuse-interface model
Junyan He, Nikhil Chandra Admal
Grain structure plays a key role in the mechanical properties of alloy materials. Engineering the grain structure requires a comprehensive understanding of the evolution of grain b…
Atomic-scale grain boundary engineering to overcome hot-cracking in additively-manufactured superalloys
Paraskevas Kontis, Edouard Chauvet, Zirong Peng +9
There are still debates regarding the mechanisms that lead to hot cracking in parts build by additive manufacturing (AM) of non-weldable Ni-based superalloys. This lack of in-depth…
2D Tunnel Field Effect Transistors (FETs) with a Stable Charge-Transfer-Type p-WSe Source
Junyang He, Nan Fang, Keigo Nakamura +4
Two-dimensional (2D) materials are highly promising for tunnel field effect transistors (TFETs) with low subthreshold swing and high drive current because the shorter tunnel distan…
