From structure mining to unsupervised exploration of atomic octahedral networks
R. Patrick Xian, Ryan J. Morelock, Ido Hadar +2
Understanding the spatial arrangements of atom-centered coordination octahedra is crucial for relating structures to properties for many materials families. Traditional case-by-cas…
Alloying behavior of wide band gap alkaline-earth chalcogenides
Samantha L. Millican, Jacob M. Clary, Christopher J. Bartel +3
Alloying is a powerful tool for tuning materials that facilitates the targeted design of desirable properties for a variety of applications. In this work, we provide a comprehensiv…
The role of decomposition reactions in assessing first-principles predictions of solid stability
Christopher J. Bartel, Alan W. Weimer, Stephan Lany +2
The performance of density functional theory (DFT) approximations for predicting materials thermodynamics is typically assessed by comparing calculated and experimentally determine…
Physical descriptor for the Gibbs energy of inorganic crystalline solids and temperature-dependent materials chemistry
Christopher J. Bartel, Samantha L. Millican, Ann M. Deml +7
The Gibbs energy, G, determines the equilibrium conditions of chemical reactions and materials stability. Despite this fundamental and ubiquitous role, G has been tabulated for onl…
First-principles calculation of intrinsic defect formation volumes in silicon
Scott A. Centoni, Babak Sadigh, George H. Gilmer +3
We present an extensive first-principles study of the pressure dependence of the formation enthalpies of all the know vacancy and self-interstitial configurations in silicon, in ea…
