Cross-Dimensional Exciton Coupling in Quantum Dot - Carbon Nanotube Hybrid Thin Films
Anna Wroblewska, Niclas S. Mueller, Mariusz Zdrojek +2
Dipole-dipole interactions provide a route to couple excitons across materials of different dimensionality. Here, we introduce hybrid films as a cross-dimensional excitonic platfor…
Raman resonances mediated by excitonic polarons in BiVO
Georgy Gordeev, Christina Hill, Angelina Gudima +2
Excitonic polarons are quasiparticles formed by a Coulomb-bound electron-hole pair with strong coupling to lattice vibrations. Despite high fundamental interest in excitonic polaro…
Dielectric Screening Inside Carbon Nanotubes
Georgy Gordeev, Sören Wasserroth, Han Li +3
Dielectric screening plays a vital role for the physical properties in the nanoscale and also alters our ability to detect and characterize nanomaterials by optical techniques. We…
Phonon-phonon coupling in bismuth vanadate over a large temperature range across the monoclinic phase
Christina Hill, Georgy Gordeev, Mael Guennou
In this work we study phonon-phonon coupling in bismuth vanadate (BiVO4), known for its second-order transition involving a variety of coupling mechanisms. Using Raman spectroscopy…
Excitonic Resonances in Coherent Anti-Stokes Raman Scattering from Single Wall Carbon Nanotubes
Georgy Gordeev, Lucas Lafeta, Benjamin Scott Flavel +2
In this work we investigate the role of exciton resonances in coherent anti-Stokes Raman scattering (er-CARS) in single walled carbon nanotubes (SWCNTs). We drive the nanotube syst…
Light Control over Chirality Selective Functionalization of Substrate Supported Carbon Nanotubes
Georgy Gordeev, Thomas Rosenkranz, Frank Hennrich +2
Diazonium reactions with carbon nanotubes form optical defects that can be used in optical and electrical circuits. We investigate a direct on-device reaction supported by c…
Nanomechanical spectroscopy of 2D materials
Jan N. Kirchhof, Yuefeng Yu, Gabriel Antheaume +7
We introduce a nanomechanical platform for fast and sensitive measurements of the spectrally-resolved optical dielectric function of 2D materials. At the heart of our approach is a…
Synthesis of Multifunctional Charge Transfer Agents: Towards Single Walled Carbon Nanotubes with Defined Covalent Functionality and Preserved π System
Alphonse Fiebor, Antonio Setaro, Andreas J. Achazi +6
The attachment of well-defined charge transfer agents to the surface of nanomaterials is an efficient strategy to control their charge density and also to tune their optical, elect…
Raman Sideband Thermometry of Single Carbyne Chains
Cla Duri Tschannen, Martin Frimmer, Georgy Gordeev +6
We demonstrate Raman sideband thermometry of single carbyne chains confined in double-walled carbon nanotubes. Our results show that carbyne's record-high Raman scattering cross se…
Moiré-induced Vibrational Coupling in Double Walled Carbon Nanotubes
Georgy Gordeev, Sören Wasserroth, Han Li +2
Moiré patterns are additional, long-range periodicities in twisted crystalline bilayers. They are known to fundamentally change the electronic states of the layers, but similar eff…
Raman Scattering Cross Section of Confined Carbyne
Cla Duri Tschannen, Georgy Gordeev, Stephanie Reich +5
We experimentally quantify the Raman scattering from individual carbyne chains confined in double-walled carbon nanotubes. We find that the resonant differential Raman cross sectio…
Atomic-Resolution Visualization and Doping Effects of Complex Structures in Intercalated Bilayer Graphene
Jason P. Bonacum, Andrew O'Hara, De-Liang Bao +9
Molecules intercalating two-dimensional (2D) materials form complex structures that have been mostly characterized by spatially averaged techniques. Here we use aberration-correcte…
