Harnessing the Diamond-Air Interface as an Efficient Photon Antenna for Solid-State Emitters
Paul Weinbrenner, Aina Lopez Benet, İdil Gözel +1
Extracting photons from defect centers is challenging due to the high refractive index of typical substrates. For nitrogen-vacancy centers in diamond, reaching saturation count rat…
Growth of few-layer molecular crystals of PTCDI on hexagonal boron nitride by microspacing air-gap sublimation
Nils LeCoutre, Tolibjon Abdurakhmonov, Paul Weinbrenner +6
Extended two-dimensional (2D) crystals of dye molecules adsorbed on 2D material substrates like boron nitride have recently become a subject of intense study, with potential applic…
When can we see micromotion? Experimental and theoretical analysis of the ChiSCAT scheme
Andrii Trelin, Jette Abel, Christian Rimmbach +3
We present an in-depth analysis of ChiSCAT, a recently introduced interferometric microscopy scheme to detect recurring micromotion events in cells. Experimentally, we demonstrate…
Planar scanning probe microscopy enables vector magnetic field imaging at the nanoscale
Paul Weinbrenner, Patricia Klar, Christian Giese +6
Planar scanning probe microscopy is a recently emerging alternative approach to tip-based scanning probe imaging. It can scan an extended planar sensor, such as a polished bulk dia…
ChiSCAT: unsupervised learning of recurrent cellular micro-motion patterns from a chaotic speckle pattern
Andrii Trelin, Sophie Kussauer, Paul Weinbrenner +4
There is considerable evidence that action potentials are accompanied by "intrinsic optical signals", such as a nanometer-scale motion of the cell membrane. Here we present ChiSCAT…
