Current density distribution for the quantum Hall effect
Serkan Sirt, Stefan Ludwig
Our microscopic understanding of the integer quantum Hall effect is still incomplete. For decades, there has been a controversial discussion about "where the current flows" if the…

Nature of current flow in the regime of the quantum Hall effect
Serkan Sirt, Matthias Kamm, Vladimir Y. Umansky +1
The integer quantum Hall effect (QHE) belongs to the most fundamental phenomena of solid state physics and has an important application as resistance standard. It serves as a basis…

Transition from edge- to bulk-currents in the quantum Hall regime
Serkan Sirt, Vladimir Y. Umansky, Afif Siddiki +1
The integer quantum Hall effect can be observed in a two-dimensional conductor penetrated by a perpendicular magnetic field and with edges connecting the current carrying contacts.…
