Metamorphic InAs/InGaAs QWs with electron mobilities exceeding
A. Benali, P. Rajak, R. Ciancio +3
We present a study on the influence of strain-relieving InAlAs buffer layers on metamorphic InAs/InGaAs quantum wells grown by molecular beam epitaxy on GaAs. Residual strain in th…
Theory of scanning gate microscopy imaging of the supercurrent distribution in a planar Josephson junction
K. Kaperek, S. Heun, M. Carrega +2
We theoretically investigate the mapping of the supercurrent distribution in a planar superconductor-normal-superconductor junction in the presence of a perpendicular magnetic fiel…
Non-equilibrium steady-states in a driven-dissipative superfluid
Ralf Labouvie, Bodhaditya Santra, Simon Heun +1
We experimentally study a driven-dissipative Josephson junction array, realized with a weakly interacting Bose Einstein condensate residing in a one-dimensional optical lattice. En…
Negative differential conductivity in an interacting quantum gas
Ralf Labouvie, Bodhaditya Santra, Simon Heun +2
Negative differential conductivity (NDC) is a widely exploited effect in modern electronic components. Here, a proof-of-principle is given for the observation of NDC in a quantum t…
