A first-principles approach to closing the "10-100 eV gap" for charge-carrier thermalization in semiconductors
Dallin O. Nielsen, Chris G. Van de Walle, Sokrates T. Pantelides +3
The present work is concerned with studying accurately the energy-loss processes that control the thermalization of hot electrons and holes that are generated by high-energy radiat…
Role of carbon and hydrogen in limiting -type doping of monoclinic (AlGa)O
Sai Mu, Mengen Wang, Joel B. Varley +3
We use hybrid density functional calculations to assess n-type doping in monoclinic (AlGa)O alloys. We focus on Si, the most promising donor dopant, and study t…
Piezoelectric effect and polarization switching in AlScN
Haochen Wang, Nicholas Adamski, Sai Mu +1
Aluminum nitride is piezoelectric and exhibits spontaneous polarization along the -axis, but the polarization cannot be switched by applying an electric field. Adding Sc to AlN…
Unusual Formation of Point Defect Complexes in the Ultra-wide Band Gap Semiconductor beta-Ga2O3
Jared M. Johnson, Zhen Chen, Joel B. Varley +10
Understanding the unique properties of ultra-wide band gap semiconductors requires detailed information about the exact nature of point defects and their role in determining the pr…
