High-pressure phase transitions in the quantum spin liquid candidate Na2Co2TeO6 probed by Raman spectroscopy
Ihsan Ahmed Kolasseri, Maria Mei Ravnebæk, Subhadip Das +5
The quasi-2D magnet Na2Co2TeO6 (NCTO) is a candidate for a Kitaev Quantum Spin Liquid (KQSL) state. Pressure-tuning in such materials is of interest as a potential method to tune t…
MoSe2/WS2 heterojunction photodiode integrated with a silicon nitride waveguide for visible light detection with high responsivity
Rivka Gherabli, S. R. K. C. Indukuri, Roy Zektzer +2
We demonstrate experimentally the realization and the characterization of a chip scale integrated photodetector for the visible and the near infrared spectral regime based on the i…
Dynamic Control of Plasmonic Colors by Voltage Actuation MEMS Cantilevers for Optical Display Applications
Zhengli Han, Christian Frydendahl, Noa Mazurski +1
Conventional optical displays using ITO (indium tin oxide) and LC (liquid crystal) materials present a lot of challenges in terms of long-term sustainability. We show here how it i…
WS2 Monolayers Coupled to Hyperbolic Metamaterial Nanoantennas: Broad Implications for Light-Matter-Interaction Applications
S. R. K. Chaitanya Indukuri, Christian Frydendahl, Jonathan Bar-David +2
Due to their atomic layer thickness, direct bandgap, mechanical robustness and other superior properties, transition metal dichalcogenides (TMDCs) monolayers are considered as an a…
Photo memtransistor based on CMOS flash memory technology on Graphene with neuromorphic applications
Christian Frydendahl, S. R. K. Chaitanya Indukuri, Meir Grajower +3
Graphene holds a great promise for a number of diverse future applications, in particular related to its easily tunable doping and Fermi level by electrostatic gating. However, as…
Giant enhancement of silicon plasmonic SWIR photodetection using nanoscale self-organised metallic films
Christian Frydendahl, Meir Grajower, Jonathan Bar-David +3
Many consumer technologies and scientific methods rely on photodetection of infrared light. We report a Schottky photodetector operating below silicon's band gap energy, through ho…
Thesis: Experimental exploration of gold semi-continuous films in the near- and far-field
Christian Frydendahl
Metallic nanostructures can support so-called plasma oscillations (plasmons). Plasmons allow for the concentration of the energy from light, down to sizes well below the convention…
Optical reconfiguration and polarization control in semi-continuous gold films close to the percolation threshold
Christian Frydendahl, Taavi Repän, Mathias Geisler +7
Controlling and confining light by exciting plasmons in resonant metallic nanostructures is an essential aspect of many new emerging optical technologies. Here we explore the possi…
White light generation and anisotropic damage in gold films near percolation threshold
Sergey M. Novikov, Christian Frydendahl, Jonas Beermann +5
Strongly enhanced and confined electromagnetic fields generated in metal nanostructures upon illumination are exploited in many emerging technologies by either fabricating sophisti…
Direct Measurement of Surface Transport on a Bulk Topological Insulator
Lucas Barreto, Lisa Kühnemund, Frederik Edler +7
Topological insulators are guaranteed to support metallic surface states on an insulating bulk, and one should thus expect that the electronic transport in these materials is domin…
