Spectral minimal partitions of unbounded metric graphs
Matthias Hofmann, James B. Kennedy, Andrea Serio
We investigate the existence or non-existence of spectral minimal partitions of unbounded metric graphs, where the operator applied to each of the partition elements is a Schröding…
Dipolar and charged localized excitons in carbon nanotubes
Jan T. Glückert, Lyudmyla Adamska, Wolfgang Schinner +4
We study both experimentally and theoretically the fundamental interplay of exciton localization and polarization in semiconducting single-walled carbon nanotubes. From Stark spect…
Antenna-enhanced Optoelectronic Probing of Carbon Nanotubes
Nina Mauser, Nicolai Hartmann, Matthias S. Hofmann +3
We report on the first antenna-enhanced optoelectronic microscopy studies on nanoscale devices. By coupling the emission and excitation to a scanning optical antenna, we are able t…
Cavity-enhanced Raman Microscopy of Individual Carbon Nanotubes
Thomas Hümmer, Jonathan Noe, Matthias S. Hofmann +3
Raman spectroscopy reveals chemically specific information and provides label-free insight into the molecular world. However, the signals are intrinsically weak and call for enhanc…
Optical signatures of quantum dot excitons in carbon nanotubes
Matthias S. Hofmann, Jan T. Glückert, Alexander Högele
We report optical studies of quantum dot excitons in individual suspended carbon nanotubes at cryogenic temperatures. Narrow optical linewidths, strongly suppressed spectral wander…
