We report single-particle photoluminescence (PL) intermittency (blinking) with high on-time fractions in colloidal CdSe quantum dots (QD) with conformal CdS shells of 1.4 nm thickness, equivalent to approximately 4 CdS monolayers. All QDs observed displayed on-time fractions > 60% with the majority > 80%. The high-on-time-fraction blinking is accompanied by fluorescence quantum yields (QY) clos...

A numerical Monte Carlo approach to evaluate transport due to spin-dependent trap-assisted tunneling in magnetic tunnel junctions has been developed. The current and the low frequency current noise is calculated. It is shown that the shot noise at spin-dependent hopping is significantly enhanced due to the Pauli spin blockade. This provides an additional characteristic for identifying spin-depe...

In the off-diagonal basis, we discuss the contributions of the non-universal gauge boson Z ′ predicted by the topcolor-assisted technicolor (TC2) model to the spin configurations and the spin correlation observable of the top quark pair production via the process e−e+ → tt̄. Our numerical results show that the production cross sections for the like-spin states, which vanish in the standard model...

Indium tin oxide (ITO) surfaces of triple junction photovoltaic cells were functionalized with oxygen evolving catalysts (OECs) based on amorphous hydrous earth-abundant metal oxides (metal = Fe, Ni, Co), obtained by straightforward Successive Ionic Layer Adsorption and Reaction (SILAR) in an aqueous environment. Functionalization with Fe(iii) oxides gave the best results, leading to photoanode...

Spin relaxation of a single electron in a weakly coupled double quantum dot is calculated numerically. The phonon-assisted spin flip is allowed by the presence of the linear and cubic spin– orbit couplings and nuclear spins. The rate is calculated as a function of the interdot coupling, the magnetic field strength and orientation, and the dot bias. In an in-plane magnetic field, the rate is str...
