Room temperature single photon emission from oxidized tungsten disulphide multilayers
Toan Trong Tran, Sumin Choi, John A. Scott +7
Two dimensional systems offer a unique platform to study light matter interaction at the nanoscale. In this work we report on robust quantum emitters fabricated by thermal oxidatio…
Engineering and localization of quantum emitters in large hexagonal boron nitride layers
Sumin Choi, Toan Trong Tran, Christopher ElBadawi +6
Hexagonal boron nitride (hBN) is a wide bandgap van der Waals material that has recently emerged as promising platform for quantum photonics experiments. In this work we study the…
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…
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…
Solar water splitting: efficiency discussion
Jurga Juodkazyte, Gediminas Seniutinas, Benjaminas Sebeka +5
The current state of the art in direct water splitting in photo-electrochemical cells (PECs) is presented together with: (i) a case study of water splitting using a simple solar ce…
UV-photoelectric effect for augmented contrast and resolution in electron microscopy
Gediminas Seniutinas, Armandas Balcytis, Saulius Juodkazis
A new tool providing material contrast control in scanning electron microscopy (SEM) is demonstrated. The approach is based on deep-UV illumination during SEM imaging and delivers…
Percolation threshold gold films on columnar coatings: characterisation for SERS applications
Armandas Balcytis, Tomas Tolenis, Xuewen Wang +4
Percolation of gold films of ~15 nm thickness was controlled to achieve the largest openings during Au deposition. Gold was evaporated on 300-nm-thick films of nanostructured porou…
