Electric-field effects on defect migration energetics in GaN
Farshid Reza, Hamdy Arkoub, Alexander S. Hauck +2
A predictive understanding of defect transport in GaN under operating electric fields is critical for assessing device reliability in high-power and radiation environments. In this…
Thermal Transport in Defective Uranium Nitride: Effects of Point Defects, Anharmonicity, and Electronic Contributions
Beihan Chen, Marat Khafizov, Zilong Hua +2
The impact of point defects on thermal transport in uranium nitride (UN) is investigated using a MLIP combined with Green-Kubo (GK) and normal mode analysis (NMA) methods over 300-…
Machine learning interatomic potential for predicting the thermal properties of uranium nitride
Beihan Chen, Zilong Hua, Jennifer K. Watkins +4
We present a combined computational and experimental investigation of the thermal properties of uranium nitride (UN), focusing on the development of a machine learning interatomic…
Evaluation of Structural Properties and Defect Energetics in AlGaN Alloys
Farshid Reza, Beihan Chen, Miaomiao Jin
AlGaN alloys are essential for high-performance optoelectronic and power devices, yet the role of composition on defect energetics remains underexplored, largely due to…
