Optical activation and detection of charge transport between individual color centers in room-temperature diamond
Artur Lozovoi, Harishankar Jayakumar, Damon Daw +5
Charge control of color centers in semiconductors promises opportunities for novel forms of sensing and quantum information processing. Here, we articulate confocal fluorescence mi…
Investigation of photon emitters in Ce-implanted hexagonal boron nitride
Gabriel I. López-Morales, Mingxing Li, Alexander Hampel +9
Color centers in hexagonal boron nitride (hBN) are presently attracting broad interest as a novel platform for nanoscale sensing and quantum information processing. Unfortunately,…
Probing metastable space-charge potentials in a wide bandgap semiconductor
Artur Lozovoi, Harishankar Jayakumar, Damon Daw +2
While the study of space charge potentials has a long history, present models are largely based on the notion of steady state equilibrium, ill-suited to describe wide bandgap semic…
Room-temperature Single Photon Emitters in Cubic Boron Nitride Nanocrystals
Gabriel I. López-Morales, Aziza Almanakly, Sitakanta Satapathy +6
Color centers in wide bandgap semiconductors are attracting broad attention as platforms for quantum technologies relying on room-temperature single-photon emission (SPE), and for…
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…
