Revisiting Coulomb diamond signatures in quantum Hall interferometers
N. Moreau, S. Faniel, F. Martins +5
Coulomb diamonds are the archetypal signatures of Coulomb blockade, a well-known charging effect mainly observed in nanometer-sized "electronic islands" tunnel-coupled with charge…
A singlet triplet hole spin qubit in planar Ge
Daniel Jirovec, Andrea Hofmann, Andrea Ballabio +14
Spin qubits are considered to be among the most promising candidates for building a quantum processor. GroupIV hole spin qubits have moved into the focus of interest due to the eas…
Fast spin exchange between two distant quantum dots
Filip K. Malinowski, Frederico Martins, Thomas B. Smith +8
The Heisenberg exchange interaction between neighboring quantum dots allows precise voltage control over spin dynamics, due to the ability to precisely control the overlap of orbit…
Thermoelectric Scanning Gate Interferometry on a Quantum Point Contact
B. Brun, F. Martins, S. Faniel +11
We introduce a new scanning probe technique derived from scanning gate microscopy (SGM) in order to investigate thermoelectric transport in two-dimensional semiconductor devices. T…
Spin of a multielectron quantum dot and its interaction with a neighboring electron
Filip K. Malinowski, Frederico Martins, Thomas B. Smith +8
We investigate the spin of a multielectron GaAs quantum dot in a sequence of nine charge occupancies, by exchange coupling the multielectron dot to a neighboring two-electron doubl…
Negative spin exchange in a multielectron quantum dot
Frederico Martins, Filip K. Malinowski, Peter D. Nissen +5
By operating a one-electron quantum dot (fabricated between a multielectron dot and a one-electron reference dot) as a spectroscopic probe, we study the spin properties of a gate-c…
