Optical Signatures of Quantum Emitters in Suspended Hexagonal Boron Nitride
Annemarie L. Exarhos, David A. Hopper, Richard R. Grote +2
Hexagonal boron nitride (h-BN) is a tantalizing material for solid-state quantum engineering. Analogously to three-dimensional wide-bandgap semiconductors like diamond, h-BN hosts…
Optimal waveform for the entrainment of oscillators perturbed by an amplitude-modulated high-frequency force
Viktor Novičenko, Irmantas Ratas
We analyze limit cycle oscillators under perturbation constructed as a product of two signals, namely, an envelope with a period close to natural period of an oscillator and a high…
The small observed scale of AGN--driven outflows, and inside--out disc quenching
Kastytis Zubovas, Andrew King
Observations of massive outflows with detectable central AGN typically find them within radii kpc. We show that this apparent size restriction is a natural result of…
Role of excited states in Shockley-Read-Hall recombination in wide-band-gap semiconductors
Audrius Alkauskas, Cyrus E. Dreyer, John L. Lyons +1
Defect-assisted recombination is an important limitation on efficiency of optoelectronic devices. However, since nonradiative capture rates decrease exponentially with energy of th…
Laser structuring for control of coupling between THz light and phonon modes
X. W. Wang, G. Seniutinas, A. Balcytis +8
Modification of surface and volume of sapphire is shown to affect reflected and transmitted light at THz spectral range. Structural modifications were made using ultra-short 230 fs…
Vibrational modes of negatively charged silicon-vacancy centers in diamond from ab initio calculations
Elisa Londero, Gergő Thiering, Lukas Razinkovas +2
Silicon-vacancy (SiV) center in diamond is a photoluminescence (PL) center with a characteristic zero-phonon line energy at 1.681 eV that acts as a solid-state single photon source…
Influence of field effects on the performance of InGaAs-based terahertz radiation detectors
Linas Minkevičius, Vincas Tamošiūnas, Martynas Kojelis +6
A detailed electrical characterization of high-performance bow-tie InGaAs based terahertz detectors is presented along with simulation results. The local surface potential and tunn…
Au-Ag-Cu nano-alloys: tailoring of permittivity
Yoshikazu Hashimoto, Gediminas Seniutinas, Armandas Balcytis +2
Precious metal alloys enables new possibilities to tailor materials for specific optical functions. Here we present a systematic study of the effects of a nanoscale alloying on the…
Influence of the substrate material on the knife-edge based profiling of tightly focused light beams
C. Huber, S. Orlov, P. Banzer +1
The performance of the knife-edge method as a beam profiling technique for tightly focused light beams depends on several parameters, such as the material and height of the knife-p…
