Polaron Self-Trapping Rates from First Principles
Mark E. Turiansky, Joel B. Varley, Audrius Alkauskas +1
Polaron formation, also known as self-trapping, is a process akin to nonradiative carrier capture at point defects or impurities. In this work, we develop the formalism to determin…
Dilute-Limit Defect Displacements Enabled by Brillouin-Zone Sampling
Mark E. Turiansky, John L. Lyons, Noam Bernstein
Defects and their interaction with the semiconductor host lattice play an essential role in a variety of technologies. When a defect transitions between two electronic states, the…
Native defects and erbium impurities in CaWO4
Minseok Choi, Mark E. Turiansky, BaiQing Zhao +2
We perform hybrid density functional calculation to study the energetics, electronic properties, optical transitions, and migration barriers of native defects in CaWO. Oxygen a…
Charge dynamics at nitrogen impurities and nitrogen-vacancy centers in diamond
Chandan Kumar Vishwakarma, J. K. Nangoi, Mark E. Turiansky +1
The nitrogen-vacancy (NV) center in diamond is the prototype quantum defect that enables a variety of diamond-based quantum technologies. However, charge-state instability and spec…
A defect in diamond with millisecond-scale spin relaxation time at room temperature
Sounak Mukherjee, Anran Li, Johannes Eberle +16
Spin defects in diamond are promising platforms for quantum sensing. The longest electron spin relaxation times () at room temperature for solid-state defects are observed in…
