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…
Machine Learning Interatomic Potential for Simulations of Carbon at Extreme Conditions
Jonathan T. Willman, Kien Nguyen-Cong, Ashley S. Williams +5
A Spectral Neighbor Analysis (SNAP) machine learning interatomic potential (MLIP) has been developed for simulations of carbon at extreme pressures (up to 5 TPa) and temperatures (…
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,…
Correlating Structural, Electronic, and Magnetic Properties of Epitaxial VSe2 Thin Films
Guannan Chen, Sean T. Howard, Aniceto B. Maghirang +9
The electronic and magnetic properties of transition metal dichalcogenides are known to be extremely sensitive to their structure. In this paper we study the effect of structure on…
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…
Novel Potassium Polynitrides at High Pressures
Brad A. Steele, Ivan I. Oleynik
Polynitrogen compounds have attracted great interest due to their potential applications as high energy density materials. Most recently, a rich variety of alkali polynitrogens (R_…
