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-…
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…
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…
Examining composition-dependent radiation response in AlGaN
Miaomiao Jin, Farshid Reza, Alexander Hauck +4
AlGaN materials have become increasingly important for electronics in radiation environments due to their robust properties. In this work, we aim to investigate the ato…
