Journal ArticleDOI
Radiation damage in nanostructured materials
Xinghang Zhang,Khalid Hattar,Youxing Chen,Lin Shao,Jin Li,Cheng Sun,Kaiyuan Yu,Nan Li,Mitra L. Taheri,Haiyan Wang,Jian Wang,Michael Nastasi +11 more
TL;DR: In this paper, the authors summarized and analyzed the current understandings on the influence of various types of internal defect sinks on reduction of radiation damage in primarily nanostructured metallic materials, and partially on nanoceramic materials.
Journal ArticleDOI
Influence of interfaces on the storage of ion-implanted He in multilayered metallic composites
TL;DR: In this paper, the ion beam mixing and He accumulation in multilayer thin films after 33keV He implantation at room temperature to a dose of 1.5×1017atoms∕cm2 were studied.
Journal ArticleDOI
Characterisation of radiation damage in W and W-based alloys from 2 MeV self-ion near-bulk implantations
TL;DR: In this paper, the displacement damage induced in W and W-5.wt.% Ta alloys by 2 MeV W+ irradiation to doses 3.3 and 3.5 W+/m2 at temperatures ranging from 300 to 750 ÂC has been characterised by transmission electron microscopy.
Journal ArticleDOI
Experimental investigation of size effects on the thermal conductivity of silicon-germanium alloy thin films.
Ramez Cheaito,John C. Duda,John C. Duda,Thomas E. Beechem,Khalid Hattar,Jon F. Ihlefeld,Douglas L. Medlin,Mark A. Rodriguez,Michael J. Campion,Michael J. Campion,Edward S. Piekos,Patrick E. Hopkins +11 more
TL;DR: It is found that the thermal conductivities of Si(1-x)Ge(x) superlattices are ultimately limited by finite size effects and sample size rather than periodicity or alloying, demonstrating the strong influence of sample size in alloyed nanosystems.
Journal ArticleDOI
Towards data-driven next-generation transmission electron microscopy.
Steven R. Spurgeon,Colin Ophus,Lewys Jones,Amanda K. Petford-Long,Sergei V. Kalinin,Matthew J. Olszta,Rafal E. Dunin-Borkowski,Norman Salmon,Khalid Hattar,Wei-Chang Yang,Renu Sharma,Yingge Du,Ann N. Chiaramonti,Haimei Zheng,Edgar C. Buck,Libor Kovarik,R. Lee Penn,Dongsheng Li,Xin Zhang,Mitsuhiro Murayama,Mitra L. Taheri +20 more
TL;DR: The open, highly integrated and data-driven microscopy architecture needed to realize transformative discoveries in the coming decade is discussed.
