Exciton and interband optical transitions in hBN single crystal
Luc Museur, Gurvan Brasse, Aurélie Pierret +8
Near band gap photoluminescence (PL) of hBN single crystal has been studied at cryogenic temperatures with synchrotron radiation excitation. The PL signal is dominated by the D-ser…
Measuring many-body effects in carbon nanotubes with a scanning tunneling microscope
Hong Lin, Jérôme Lagoute, Vincent Repain +6
Electron-electron interactions and excitons in carbon nanotubes are locally measured by combining Scanning tunneling spectroscopy and optical absorption in bundles of nanotubes. Th…
Origin of the excitonic recombinations in hexagonal boron nitride by spatially resolved cathodoluminescence spectroscopy
Périne Jaffrennou, Julien Barjon, Jean-Sébastien Lauret +3
The excitonic recombinations in hexagonal boron nitride (hBN) are investigated with spatially resolved cathodoluminescence spectroscopy in the UV range. Cathodoluminescence images…
