Bullseye dielectric cavities for photon collection from a surface-mounted quantum-light-emitter
Reza Hekmati, John P. Hadden, Annie Mathew +3
Coupling light from a point source to a propagating mode is an important problem in nano-photonics and is essential for many applications in quantum optics. Circular "bullseye" cav…
High resolution nanosecond spectroscopy of even-parity Rydberg excitons in CuO
Joshua P. Rogers, Liam A. P. Gallagher, Danielle Pizzey +6
We present a study of even parity Rydberg exciton states in cuprous oxide using time-resolved second harmonic generation (SHG). Excitonic states with principal quantum number n = 5…
Microwave-optical coupling via Rydberg excitons in cuprous oxide
Liam A. P. Gallagher, Joshua P. Rogers, Jon D. Pritchett +9
We report exciton-mediated coupling between microwave and optical fields in cuprous oxide (CuO) at low temperatures. Rydberg excitonic states with principal quantum number up t…
Rydberg Excitons in Synthetic Cuprous Oxide (CuO)
Stephen A. Lynch, Chris Hodges, Soumen Mandal +8
High-lying Rydberg states of Mott-Wannier excitons are receiving considerable interest due to the possibility of adding long-range interactions to the physics of exciton-polaritons…
Tail-states induced semiconductor-toconductor like transition under sub-bandgap light excitation in the zinc-tin-oxide photothinfilm transistors
Soumen Dhara, Kham M. Niang, Andrew J. Flewitt +2
We report on a giant persistent photoconductivity (PPC) induced semiconductor-to-conductor like transition in zinc-tin-oxide (ZTO) photo-thinfilm transistors (TFT). The active ZTO…
Surface zeta potential and diamond seeding on gallium nitride films
Soumen Mandal, Evan L. H. Thomas, Callum Middleton +9
Measurement of zeta potential of Ga and N-face gallium nitride has been carried out as function of pH. Both the faces show negative zeta potential in the pH range 5.5-9. The Ga fac…
