The spin-orbit interaction is a crucial element of many semiconductor spintronic technologies. Here we report the first experimental observation, by magneto-optical spectroscopy, of a remarkable consequence of the spin-orbit interaction for holes confined in the molecular states of coupled quantum dots. As the thickness of the barrier separating two coupled quantum dots is increased, the molecular ground state changes character from a bonding orbital to an antibonding orbital. This result is…

Electrically tunable g factors in quantum dot molecular spin states.
A phenomenological model for the change in g factor based on resonant changes in the amplitude of the wave function in the barrier due to the formation of bonding and antibonding orbitals is proposed.
Optical pumping of a single hole spin in a quantum dot
High fidelity initialization of a single hole spin confined to a self-assembled quantum dot by optical pumping is demonstrated, demonstrating a negligible hole spin hyperfine interaction and suggesting a route to the realization of solid-state quantum networks that can intra-convert the spin state with the polarization of a photon.
Coupled quantum dots fabricated by cleaved edge overgrowth: from artificial atoms to molecules
The formation of bonding and antibonding states between two such "artificial atoms" was studied as a function of quantum dot separation by microscopic photoluminescence (PL) spectroscopy.
Coupling and entangling of quantum states in quantum dot molecules.
The electron-hole complex is shown to be equivalent to entangled states of two interacting spins in a pair of vertically aligned, self-assembled quantum dots.
Observation of extremely slow hole spin relaxation in self-assembled quantum dots
We report the measurement of extremely slow hole spin relaxation dynamics in small ensembles of self-assembled InGaAs quantum dots. Individual spin oriented holes are optically created in the lowest
Coupling and Strain Effects in Vertically Stacked Double InAs/GaAs Quantum Dots: Tight-Binding Approach
The empirical tight-binding approach is used to study atomic-scale effects on electronic coupling in vertically stacked, self-assembled InAs/GaAs quantum dots. A model with unstrained dots is first
Theory of excitonic spectra and entanglement engineering in dot molecules.
Results of correlated pseudopotential calculations of an exciton in a pair of vertically stacked InGaAs/GaAs dots are presented and ways to spectroscopically identify and maximize the entanglement of exciton states are suggested.
Hole levels in InAs self-assembled quantum dots
We measure the energy levels and charging spectra of holes in self-assembled InAs quantum dots using capacitance-voltage and polarized photoluminescence spectroscopy in high m agnetic fields. The
Strain effects on the electronic structure of strongly coupled self-assembled InAs/GaAs quantum dots : Tight-binding approach
We present an atomistic tight-binding study of the electronic structure and optical properties of vertically stacked, double, self-assembled, InAs/ GaAs quantum dots. The investigated dots are
