Report

Resonant Raman scattering of surface phonon polaritons mediated by excitons in WSe$_2$ films

Autor: Zhou, L., Wirth, K., Bui, M. N., Rani, R., Grützmacher, D., Taubner, T., Kardynał, B. E.

Surface phonon-polaritons propagating along interfaces of polar dielectrics coexist with excitons in many van der Waals heterostructures, so understanding their mutual interactions is of great interest. Here, we investigate the type I surface phonon

Report

An avalanche-photodiode-based photon-number-resolving detector

Autor: Kardynal, B. E., Yuan, Z. L., Shields, A. J.

Publikováno v: Nature Photonics 2, 425-428 (2008)

Avalanche photodiodes are widely used as practical detectors of single photons.1 Although conventional devices respond to one or more photons, they cannot resolve the number in the incident pulse or short time interval. However, such photon number re

Report

High speed single photon detection in the near-infrared

Autor: Yuan, Z. L., Kardynal, B. E., Sharpe, A. W., Shields, A. J.

Publikováno v: Appl. Phys. Lett. 91, 041114(2007)

InGaAs avalanche photodiodes (APDs) are convenient for single photon detection in the near-infrared (NIR) including the fibre communication bands (1.31/1.55 $\mu$m). However, to suppress afterpulse noise due to trapped avalanche charge, they must be

Low-energy Se ion implantation in MoS₂ monolayers

Autor: Bui, M. N., Rost, S., Auge, M., Tu, J.-S., Zhou, L., Aguilera, I., Blügel, S., Ghorbani Asl, M., Krasheninnikov, A., Hashemi, A., Komsa, H.-P., Jin, L., Kibkalo, L., O’Connell, E. N., Ramasse, Q. M., Bangert, U., Hofsäss, H. C., Grützmacher, D., Kardynal, B. E.

In this work, we study ultra-low energy implantation into MoS₂ monolayers to evaluate the potential of the technique in two-dimensional materials technology. We use 80 Se⁺ ions at the energy of 20 eV and with fluences up to 5.0 · 10¹⁴ cm⁻²
