High-Precision Excited-State Nuclear Recoil Spectroscopy with Superconducting Sensors
C. Bray, S. Fretwell, L. A. Zepeda-Ruiz +30
Superconducting sensors doped with rare isotopes have recently demonstrated powerful sensing performance for sub-keV radiation from nuclear decay. Here, we report the first high-re…
Extreme Metastability of Diamond and its Transformation to BC8 Post-Diamond Phase of Carbon
Kien Nguyen-Cong, Jonathan T. Willman, Joseph M. Gonzalez +9
Diamond possesses exceptional physical properties due to its remarkably strong carbon-carbon bonding, leading to significant resilience to structural transformations at very high p…
Metal hardening in atomistic detail
Luis A. Zepeda-Ruiz, Alexander Stukowski, Tomas Oppelstrup +4
Through millennia humans exploited the natural property of metals to get stronger or hardened when mechanically deformed. Ultimately rooted in the motion of dislocations, mechanism…
Probing the ultimate limits of metal plasticity
Luis A. Zepeda-Ruiz, Alexander Stukowski, Tomas Oppelstrup +1
Along with high strength, plasticity is what makes metals so widely usable in our material world. Both strength and plasticity properties of a metal are defined by the motion of di…
Atomistics of vapor-liquid-solid nanowire growth
Hailong Wang, Luis A. Zepeda-Ruiz, George H. Gilmer +1
Vapor-liquid-solid (VLS) route and its variants are routinely used for scalable synthesis of semiconducting nanowires yet the fundamental growth processes remain unknown. Here, we…
A scalable parallel Monte Carlo algorithm for atomistic simulations of precipitation in alloys
Babak Sadigh, Paul Erhart, Alexander Stukowski +3
We present an extension of the semi-grandcanonical (SGC) ensemble that we refer to as the variance-constrained semi-grandcanonical (VC-SGC) ensemble. It allows for transmutation Mo…
Strongly Non-Arrhenius Self-Interstitial Diffusion in Vanadium
Luis A. Zepeda-Ruiz, Joerg Rottler, Seungwu Han +3
We study diffusion of self-interstitial atoms (SIAs) in vanadium via molecular dynamics simulations. The <111>-split interstitials are observed to diffuse one-dimensionally at low…
