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…
Metastable Carbon at Extreme Conditions
Ashley S. Williams, Kien Nguyen-Cong, Jonathan T. Willman +1
Carbon at extreme conditions is the focus of intensive scientific inquiry due to its importance for applications in inertial confinement fusion experiments and for understanding th…
Crystal Structure of Silver Pentazolates AgN5 and AgN6
Ashley S. Williams, Kien Nguyen Cong, Joseph M. Gonzalez +1
Silver pentazolate, a high energy density compound containing cyclo-N5- anion, has recently been synthesized at ambient conditions. However, due to high sensitivity to irradiation,…
Novel Rubidium Poly-Nitrogen Materials at High Pressure
Ashley S. Williams, Brad A. Steele, van I. Oleynik
First-principles crystal structure search is performed to predict novel rubidium poly-nitrogen materials at high pressure by varying the stoichiometry, i. e. relative quantities of…
