[HTML][HTML] Exciton-dominated optical response of ultra-narrow graphene nanoribbons

R Denk, M Hohage, P Zeppenfeld, J Cai… - Nature …, 2014 - nature.com
Narrow graphene nanoribbons exhibit substantial electronic bandgaps and optical
properties fundamentally different from those of graphene. Unlike graphene—which shows a …

Electric-field-tuned color in photonic crystal elastomers

…, R Kaltseis, S Bauer, I Graz, R Denk… - Applied Physics …, 2012 - pubs.aip.org
Electrically tuned photonic crystals are produced by applying fields across shear-assembled
elastomeric polymer opal thin films. At increasing voltages, the polymer opal films stretch …

Probing optical excitations in chevron-like armchair graphene nanoribbons

R Denk, A Lodi-Rizzini, S Wang, M Hohage… - Nanoscale, 2017 - pubs.rsc.org
The bottom-up fabrication of graphene nanoribbons (GNRs) has opened new opportunities
to specifically tune their electronic and optical properties by precisely controlling their atomic …

Layer resolved evolution of the optical properties of α-sexithiophene thin films

…, S Berkebile, G Weidlinger, M Denk, R Denk… - Physical Chemistry …, 2012 - pubs.rsc.org
We report a combined reflectance difference spectroscopy and scanning tunneling microscopy
study of ultrathin α-sexithiophene (6T) films deposited on the Cu(110)-(2×1)O surface. …

Reflectance anisotropy spectroscopy as a tool for mechanical characterization of metallic thin films

…, M Schamel, AS Sologubenko, R Denk… - Journal of Physics D …, 2015 - iopscience.iop.org
In the present work reflectance anisotropy spectroscopy (RAS) is evaluated as a new tool for
the mechanical characterization of metallic thin films on viscoelastic substrates. Cu and Cu–…
