Elastic and inelastic scanning tunneling spectroscopy on iron-based superconductors

Creators

Description

This thesis describes an experimental study of the pairing mechanism in unconventional superconductors and their manifestations in scanning tunneling spectroscopy (STS). It was found that in contrast to planar tunneling junctions, where elastic processes dominate, inelastic contributions to the tunneling current cannot be neglected in the case of STS on conventional as well as on unconventional superconductors. The measurements were performed with three different low-temperature scanning tunneling microscope (STM) setups down to 30 mK on the following systems: lead (Pb), SrFe2(As1-xPx)2, bulk FeSe and a single layer FeSe on SrTiO3.
