Characterization of Chromium Impurities in -GaO
Mark E. Turiansky, Sai Mu, Lukas Razinkovas +8
Chromium is a common transition-metal impurity that is easily incorporated during crystal growth. It is perhaps best known for giving rise to the 694.3 nm (1.786 eV) emission in Cr…
First-principles theory of direct-gap optical emission in hexagonal Ge and its enhancement via strain engineering
Christopher A. Broderick, Xie Zhang, Mark E. Turiansky +1
The emergence of hexagonal Ge (2H-Ge) as a candidate direct-gap group-IV semiconductor for Si photonics mandates rigorous understanding of its optoelectronic properties. Theoretica…
Rapid, in-situ neutralization of nitrogen- and silicon-vacancy centers in diamond using above-band-gap optical excitation
Christian Pederson, Nicholas S. Yama, Lane Beale +2
The charge state of a quantum point defect in a solid state host strongly determines its optical and spin characteristics. Consequently, techniques for controlling the charge state…
Dielectric Loss due to Charged-Defect Acoustic Phonon Emission
Mark E. Turiansky, Chris G. Van de Walle
The coherence times of state-of-the-art superconducting qubits are limited by bulk dielectric loss, yet the microscopic mechanism leading to this loss is unclear. Here we propose t…
Rational Design of Efficient Defect-Based Quantum Emitters
Mark E. Turiansky, Kamyar Parto, Galan Moody +1
Single-photon emitters are an essential component of quantum networks, and defects or impurities in semiconductors are a promising platform to realize such quantum emitters. Here w…
