Discovering Superhard B-N-O Compounds by Iterative Machine Learning and Evolutionary Structure Predictions
Wei-Chih Chen, Yogesh K. Vohra, Cheng-Chien Chen
We search for new superhard B-N-O compounds with an iterative machine learning (ML) procedure, where ML models are trained using sample crystal structures from evolutionary algorit…
Machine Learning and Evolutionary Prediction of Superhard B-C-N Compounds
Wei-Chih Chen, Joanna N. Schmidt, Da Yan +2
We build random forests models to predict elastic properties and mechanical hardness of a compound, using only its chemical formula as input. The model training uses over 10,000 ta…
Growth Morphology of Boron Doped Single Crystal Diamond
S. K. Karna, Y. K. Vohra, P. Kung +1
Boron-doped single crystal diamond films were grown homoepitaxially on synthetic (100) Type Ib diamond substrates using microwave plasma assisted chemical vapor deposition. A modif…
Optical and Electrical Characterization of Boron-Doped Diamond
Sunil K. Karna, Yogesh. K. Vohra, Samuel T. Weir
The boron-doped single crystal diamond films were grown homoepitaxially on synthetic (100) oriented Type Ib diamond substrates using a Microwave Plasma Chemical Vapor Deposition (M…
High pressure transport properties of the topological insulator Bi2Se3
J. J. Hamlin, J. R. Jeffries, N. P. Butch +6
We report x-ray diffraction, electrical resistivity, and magnetoresistance measurements on Bi2Se3 under high pressure and low temperature conditions. Pressure induces profound chan…
Structural Phase Transformations in Iron-Chalcogen under High Pressures
Andrew K. Stemshorn, Yogesh K. Vohra, Phillip M. Wu +4
We report high pressure structural phase transformation sequence in a layered Iron-based superconducting compound FeSe0.3Te0.7 to 31 GPa at room temperature. The ambient pressure P…
