An Ultra-High Vacuum Scanning Tunneling Microscope with Pulse Tube and Joule-Thomson cooling operating at sub-pm z-noise
Marcus Eßer, Marco Pratzer, Marc Frömming +4
We describe a compact ultra-high vacuum (UHV) scanning tunneling microscope (STM) system that does not need any external supply of cooling liquids. It achieves temperatures down to…
Origin and evolution of surface spin current in topological insulators
André Dankert, Priyamvada Bhaskar, Dmitrii Khokhriakov +6
The Dirac surface states of topological insulators offer a unique possibility for creating spin polarized charge currents due to the spin-momentum locking. Here we demonstrate that…
Mask aligner for ultrahigh vacuum with capacitive distance control
Priyamvada Bhaskar, Simon Mathioudakis, Tim Olschewski +5
We present a mask aligner driven by three piezo motors which guides and aligns a SiN shadow mask under capacitive control towards a sample surface. The three capacitors for read ou…
Mapping the band structure of GeSbTe phase change alloys around the Fermi level
Jens Kellner, Gustav Bihlmayer, Marcus Liebmann +16
Phase change alloys are used for non-volatile random access memories exploiting the conductivity contrast between amorphous and metastable, crystalline phase. However, this contras…
