We describe basic properties of hysteretic funnel-like structures in the tunneling current through two weakly coupled vertical quantum dots on application of a weak magnetic field applied parallel to the current in two regimes (referred to as I and I

We study the magnetic (B -) field evolution of single-particle levels in one dot by observing resonant tunnelling (RT) between two weakly coupled vertical quantum dots in series. The B -field dependence of the RT current peaks in the spectrum follows

We report on the basic properties of recently observed magnetic field resonance, induced time dependent oscillation, and hysteresis effects in the current flowing through two weakly coupled vertical quantum dots at high source-drain bias (up to a few

We measure the interdot charge relaxation time T_1 of a single electron trapped in an accumulation mode Si/SiGe double quantum dot. The energy level structure of the charge qubit is determined using photon assisted tunneling, which reveals the presen

We outline the properties of the hyperfine-induced funnel structure observed in the two-electron spin blockade region of a weakly coupled vertical double quantum dot device. Hysteretic steps in the leakage current occur due to dynamic nuclear polariz

Significant incentives remain for decreasing the mean solids and water content and their variability in combined extraction froth from Athabasaca oil sands, both in the hot water processes now commercially implemented, and in projected processes typi

We outline the properties of fine structure in the high bias (∼10-100 mV) current of a weakly coupled vertical double-dot device close to "pinch-off". Two features of particular interest at 0 T are modulations in the strength along the length of th

With two weakly coupled vertical quantum dots we investigate how fine features in the tunneling current caused by electron‐spin nuclear‐spin coupling behave throughout the two‐electron spin blockade regime with an out‐of‐plane magnetic fiel
