Evolution of electronic and magnetic properties of SrIrO under strain
Ekaterina M. Parschke, Wei-Chih Chen, Rajyavardhan Ray +1
Motivated by properties-controlling potential of the strain, we investigate strain dependence of structure, electronic and magnetic properties of SrIrO using complementary…
p x n-Type Transverse Thermoelectrics in a Type-II Weyl Semimetal TaIrTe4
Josh Mutch, Wei-Chih Chen, Cheng-Yi Huang +3
p x n-type materials refer to materials with a p-type Seebeck coefficient in one direction and a n-type coefficient in the orthogonal direction. This type of materials allows for a…
Superconducting Phases of the Square-Lattice Extended Hubbard Model
Wei-Chih Chen, Yao Wang, Cheng-Chien Chen
We study the square-lattice extended Hubbard model with on-site and nearest-neighbor interactions by exact diagonalization. We show that non-equilibrium quench dynamics can…
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…
LaN Structural and Topological Transitions Driven by Temperature and Pressure
Wei-Chih Chen, Chia-Min Lin, Joseph Maciejko +1
We study lanthanum mononitride LaN by first-principles calculations. The commonly reported rock-salt structure of symmetry for rare-earth monopnictides is found dynami…
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…
First-Principles Study of Strain Effect on Thermoelectric Properties of LaP and LaAs
Chia-Min Lin, Wei-Chih Chen, Cheng-Chien Chen
Rare-earth monopnictides have attracted much attention due to their unusual electronic and topological properties for potential device applications. Here, we study rock-salt struct…
Evidence for a strain tuned topological phase transition in ZrTe5
Joshua Mutch, Wei-Chih Chen, Preston Went +5
A phase transition between topologically distinct insulating phases involves closing and reopening of the bandgap. Close to this topological phase transition, the bulk energy spect…
