Stacking angle dependent multiple excitonic resonances in bilayer tungsten diselenide

Autor: Arora Ankit, Nayak Pramoda K., Dixit Tejendra, Ganapathi Kolla Lakshmi, Krishnan Ananth, Rao Mamidanna Sri Ramachandra

Publikováno v: Nanophotonics, Vol 9, Iss 12, Pp 3881-3887 (2020)

We report on multiple excitonic resonances in bilayer tungsten diselenide (BL-WSe2) stacked at different angles and demonstrate the use of the stacking angle to control the occurrence of these excitations. BL-WSe2 with different stacking angles were

New insights into nonclassical light emission from defects in multi-layer hexagonal boron nitride

Autor: Bommer Alexander, Becher Christoph

Publikováno v: Nanophotonics, Vol 8, Iss 11, Pp 2041-2048 (2019)

In recent years, mono-layers and multi-layers of hexagonal boron nitride (hBN) have been demonstrated as host materials for localized atomic defects that can be used as emitters for ultra-bright, non-classical light. The origin of the emission, howev

Single particle dark-field spectroscopy of spherical dimers with down to sub-10 nm gaps fabricated by the annealing of nano-pillars

Autor: Dickreuter Simon, Kern Dieter P., Fleischer Monika

Publikováno v: Nanophotonics, Vol 7, Iss 7, Pp 1317-1324 (2018)

In this paper we present a method for the fabrication of plasmonic spherical dimers and oligomers with narrow gaps and tunable distances. High-aspect-ratio nano-pillars are created by the two-step evaporation of gold on structured substrates. By usin

Plasmonic circuits for manipulating optical information

Autor: Davis Timothy J., Gómez Daniel E., Roberts Ann

Publikováno v: Nanophotonics, Vol 6, Iss 3, Pp 543-559 (2016)

Surface plasmons excited by light in metal structures provide a means for manipulating optical energy at the nanoscale. Plasmons are associated with the collective oscillations of conduction electrons in metals and play a role intermediate between ph

Tuning the influence of metal nanoparticles on ZnO photoluminescence by atomic-layer-deposited dielectric spacer

Autor: Liu Monan, Chen Rui, Adamo Giorgio, MacDonald Kevin F., Sie Edbert J., Sum Tze Chien, Zheludev Nikolay I., Sun Handong, Fan Hong Jin

Publikováno v: Nanophotonics, Vol 2, Iss 2, Pp 153-160 (2013)

There is increasing interest in tuning the optical and optoelectronic properties of semiconductor nanostructures using metal nanoparticles in their applications in light-emitting and detection devices. In this work we study the effect of a dielectric
