We study single electron transport across a single Bi dopant in a silicon nanotransistor to assess how the strong hyperfine coupling with the Bi nuclear spin I = 9/2 affects the transport characteristics of the device. In the sequential tunneling regime we find that at, temperatures in the range of 100 mK, dI/dV curves reflect the zero field hyperfine splitting as well as its evolution under an applied magnetic field. Our non-equilibrium quantum simulations show that nuclear spins can be…

Inelastic electron tunneling spectroscopy of a single nuclear spin.

This work shows that the energy levels of a single nuclear spin can be measured by means of inelastic electron tunneling spectroscopy (IETS), and finds that the hyperfine coupling opens new transport channels which can be resolved at experimentally accessible temperatures.

Transport spectroscopy of a single dopant in a gated silicon nanowire.

Spectroscopy of a single dopant atom in silicon by resonant tunneling between source and drain of a gated nanowire etched from silicon on insulator finds excited states and Zeeman splitting under magnetic field present large energies potentially useful to build atomic scale devices.

Single-electron transport in electrically tunable nanomagnets.

Evidence is presented that this single-electron transistor based upon a II-VI semiconductor quantum dot doped with a single-Mn ion behaves like a quantum nanomagnet whose total spin and magnetic anisotropy depend dramatically both on the number of carriers and their orbital nature.

Observation of hysteretic transport due to dynamic nuclear spin polarization in a GaAs lateral double quantum dot.

A new transport feature in a GaAs lateral double quantum dot that emerges for magnetic-field sweeps and shows hysteresis due to dynamic nuclear spin polarization (DNP) opens up the possibility of controlling electron and nuclear spin states via dc transport.

Single-dopant resonance in a single-electron transistor

Single dopants in semiconductor nanostructures have been studied in great details recently as they are good candidates for quantum bits, provided they are coupled to a detector. Here we report

Dynamic nuclear polarization with single electron spins.

A self-limiting pulse sequence is developed that allows the steady-state nuclear polarization to be set using a gate voltage and the resulting Overhauser field approaches 80 mT, in agreement with a simple rate-equation model.

Large nuclear overhauser fields detected in vertically coupled double quantum dots.

The electrical induction and detection of dynamic nuclear polarization in the spin-blockade regime of double GaAs vertical quantum dots and the largest Overhauser field observed was about 4 T, corresponding to a nuclear polarization approximately 40% for the electronic g factor typical of these devices.
