Charge-state control of carbon-related optical absorption in AlN
Helen C. Robinson, Daniil Danilin, Md Shafiqul Islam Mollik +5
Sub-bandgap optical absorption in AlN between 2 eV and 4 eV is widely observed, but its microscopic origin remains contested. Using photo-induced electron paramagnetic resonance (p…
Nonradiative quenching of EPR signals in germanium-doped AlGaN: evidence for DX-center formation
Jason Forbus, Darshana Wickramaratne, John L. Lyons +1
We present photo-electron paramagnetic resonance (EPR) measurements and first-principles calculations that indicate germanium (Ge) is a DX-center in AlGaN. Our photo-EPR measuremen…
Direct evidence for carbon incorporation on the nitrogen site in AlN
Darshana Wickramaratne, Mackenzie Siford, Md Shafiqul Islam Mollik +2
We use photo-electron paramagnetic resonance (EPR) measurements and first-principles calculations to identify and explain the properties of carbon in AlN. We present clear evidence…
High Field Phenomena of Qubits
J. van Tol, G. W. Morley, S. Takahashi +3
Electron and nuclear spins are very promising candidates to serve as quantum bits (qubits) for proposed quantum computers, as the spin degrees of freedom are relatively isolated fr…
