Journal ArticleDOI
Loop and void damage during heavy ion irradiation on nanocrystalline and coarse grained tungsten: Microstructure, effect of dpa rate, temperature, and grain size
Osman El-Atwani,E. Esquivel,Mert Efe,Eda Aydogan,Yongqiang Wang,Enrique Martínez,Stuart A. Maloy +6 more
TL;DR: In this article, the displacement damage through heavy ion irradiation was studied on two tungsten grades (coarse grained Tungsten (CGW) and nanocrystalline and ultrafine grained (NCW) using different displacement per atom rates and different irradiation temperatures (RT and 1050 K).
Journal ArticleDOI
Nanochannel structures in W enhance radiation tolerance
Wenjing Qin,Feng Ren,R.P. Doerner,Guo Wei,Yawei Lv,Sheng Chang,Ming Tang,Huiqiu Deng,Changzhong Jiang,Yongqiang Wang +9 more
TL;DR: In this article, a new strategy was proposed to address the root causes of bubble nucleation and fuzz formation by concurrently releasing He outside of the Tungsten matrix through the nano-engineered channel structure (nanochannels).
Journal ArticleDOI
Chemical manipulation of hydrogen induced high p-type and n-type conductivity in Ga2O3.
Minhazul Islam,Maciej Oskar Liedke,David Winarski,Maik Butterling,Andreas Wagner,Peter Hosemann,Yongqiang Wang,Blas P. Uberuaga,Farida Selim +8 more
TL;DR: This work illustrates a new approach that allows a tunable and reversible way of modifying the conductivity of semiconductors and it is expected to have profound implications on semiconductor field.
Journal ArticleDOI
Interpreting nanovoids in atom probe tomography data for accurate local compositional measurements
Xing Wang,Constantinos Hatzoglou,Brian T. Sneed,Zhe Fan,Wei Guo,Ke Jin,Di Chen,Hongbin Bei,Yongqiang Wang,William J. Weber,William J. Weber,Yanwen Zhang,Yanwen Zhang,Baptiste Gault,Karren L. More,François Vurpillot,Jonathan D. Poplawsky +16 more
TL;DR: It is revealed that voids can lead to either an increase or a decrease in local atomic densities in the APT reconstruction and a general approach is provided for quantifying chemical segregations near voids within an APT dataset, in which the composition can be directly determined with a higher accuracy than STEM-based techniques.
Journal ArticleDOI
Helium irradiated cavity formation and defect energetics in Ni-based binary single-phase concentrated solid solution alloys
Zhe Fan,Shijun Zhao,Ke Jin,Di Chen,Yury N. Osetskiy,Yongqiang Wang,Hongbin Bei,Karren L. More,Yanwen Zhang,Yanwen Zhang +9 more
TL;DR: In this paper, the authors show that alloying elements have a clear impact on He cavity formation and density distribution in single-phase concentrated solid solution alloys (SP CSAs).
