Hunter B. Schonfeld, Elizabeth Golightly, Milena Milich +7
Advances in next-generation hypersonic hot structures, high heat-flux fusion or fission components, and laser based additive manufacturing depend on reliable solid state thermal co…
Epitaxial growth and semiconductor properties of NiGa2O4 spinel for Ga2O3/NiO interfaces
Kingsley Egbo, Emily M. Garrity, Shivashree Shivamade Gowda +8
Unintentionally formed interfacial layers are ubiquitous in semiconductor devices that operate at extreme conditions. However, these layers' structure and properties often remain u…
Ruddlesden-Popper chalcogenides push the limit of mechanical stiffness and glass-like thermal conductivity in single crystals
Md Shafkat Bin Hoque, Eric R. Hoglund, Boyang Zhao +20
Insulating materials featuring ultralow thermal conductivity for diverse applications also require robust mechanical properties. Conventional thinking, however, which correlates st…
