Donor-bound-exciton strain microscopy in silicon devices
Pierandrea Conti, Siddharth Dhomkar, Philipp Ross +2
We explore the effects of stress on silicon donor bound exciton () transitions in bulk silicon and in microfabricated silicon devices. We first study …
Plasmonics enabled atomically thin linearly polarized emitter at room temperature
Bidisha Roy, Maex Blauth, Siddharth Dhomkar +3
Two-dimensional transition metal di-chalcogenide semiconductors provide unique possibilities to investigate strongly confined excitonic physics and a plasmonic platform integrable…
Dynamics of frequency-swept nuclear spin optical pumping in powdered diamond at low magnetic fields
Pablo R. Zangara, Siddharth Dhomkar, Ashok Ajoy +7
A broad effort is underway to improve the sensitivity of nuclear magnetic resonance through the use of dynamic nuclear polarization. Nitrogen-vacancy (NV) centers in diamond offer…
Spin readout via spin-to-charge conversion in bulk diamond nitrogen-vacancy ensembles
Harishankar Jayakumar, Siddharth Dhomkar, Jacob Henshaw +1
We demonstrate optical readout of ensembles of nitrogen-vacancy(NV) center spins in a bulk diamond sample via spin-to-charge conversion. A high power 594 nm laser is utilized to se…
Charge dynamics in near-surface, variable-density ensembles of nitrogen-vacancy centers in diamond
Siddharth Dhomkar, Harishankar Jayakumar, Pablo R. Zangara +1
Although the spin properties of superficial shallow nitrogen-vacancy (NV) centers have been the subject of extensive scrutiny, considerably less attention has been devoted to study…
On-Demand Generation of Neutral and Negatively-Charged Silicon-Vacancy Centers in Diamond
Siddharth Dhomkar, Pablo R. Zangara, Jacob Henshaw +1
Point defects in wide-bandgap semiconductors are emerging as versatile resources for nanoscale sensing and quantum information science but our understanding of the photo-ionization…
