Journal ArticleDOI
Intersublevel Spectroscopy on Single InAs-Quantum Dots by Terahertz Near-Field Microscopy
Rainer Jacob,Stephan Winnerl,Markus Fehrenbacher,Jayeeta Bhattacharyya,Harald Schneider,Marc Tobias Wenzel,Hans-Georg von Ribbeck,Lukas M. Eng,Paola Atkinson,Oliver G. Schmidt,Manfred Helm +10 more
TL;DR: Using scattering-type near-field infrared microscopy in combination with a free-electron laser, intersublevel transitions in buried single InAs quantum dots are investigated and signals from bound-to-bound transitions of single electrons in a probe volume of the order of (100 nm)(3).
Journal ArticleDOI
Quantitative determination of the charge carrier concentration of ion implanted silicon by IR-near-field spectroscopy
Rainer Jacob,Stephan Winnerl,Harald Schneider,Manfred Helm,Marc Tobias Wenzel,Hans-Georg von Ribbeck,Lukas M. Eng,Susanne C. Kehr +7 more
TL;DR: A combination of a scattering-type near-field infrared microscope with a free-electron laser as an intense, tunable radiation source to spatially and spectrally resolve buried doped layers in silicon yields quantitatively correct values for the concentration of the activated carriers.
Journal ArticleDOI
Near-field resonance shifts of ferroelectric barium titanate domains upon low-temperature phase transition
TL;DR: In this article, the authors apply the s-SNOM possibilities to quantify low-temperature phase transitions in barium titanate single crystals by both temperature-dependent resonance spectroscopy and domain distribution imaging.
Proceedings ArticleDOI
Scattering near-field microscopy in the THz region using a free-electron laser
TL;DR: In this paper, a scattering-type scanning near-field optical micro-spectroscopy (s-SNOM) investigations successfully operated in the THz range with a wavelength independent spatial resolution of < 150 nm.
Journal ArticleDOI
