Topological Frenkel excitons in 2D molecular crystals
Quentin Stein, Sidhartha Nayak, Song Jiang +7
Collective molecular excitations govern energy transport in light-harvesting and optoelectronic materials. Theory predicts that excitonic band topology can generate edge-confined s…
Momentum-Locked Edge Excitons in 2D Molecular Crystals
Sidhartha Nayak, Alex Boeglin, Quentin Stein +4
In molecular crystals, molecular excitations can hybridize into collective Frenkel excitons. Here we show that doubly degenerate excitations in planar two-dimensional molecular cry…
Gating single-molecule fluorescence with electrons
Katharina Kaiser, Michelangelo Romeo, Fabrice Scheurer +2
Tip-enhanced photoluminescence (TEPL) measurements are performed with sub-nanometer spatial resolution on individual molecules decoupled from a metallic substrate by a thin NaCl la…
Electrically driven cascaded photon-emission in a single molecule
Katharina Kaiser, Anna Rosławska, Michelangelo Romeo +3
Controlling electrically-stimulated quantum light sources (QLS) is key for developing integrated and low-scale quantum devices. The mechanisms leading to quantum emission are compl…
Fluorescent single-molecule STM probe
Niklas Friedrich, Anna Roslawska, Xabier Arrieta +7
The plasmonic tip of a scanning tunnelling microscope (STM) is functionalized with a single fluorescent molecule and is scanned on a plasmonic substrate. The tunneling current flow…
