The two-photon absorption coefficient β in InP has been measured in the wavelength range of 1640 to 1800 nm by the Z-scan technique in relatively thick materials. The values of β have been evaluated from the fit to the equation including the spatia

A hyperon–nucleon scattering experiment, KEK-PS E289, was carried out at the K2 beam line in KEK. We adopted a scintillating fiber active target as a hydrogen target for hyperon production and subsequent hyperon–nucleon scattering. We collected m

We have performed a hyperon-proton scattering experiment with a scintillating fiber active target. The Σ − p, Λ p and Σ + p scattering have been studied with the same experimental setup. In this paper, we present the differential cross sections

The low temperature magneto-resistance of quasi-ballistic, corrugated quantum wires has been studied. In the region near zero magnetic field, the magneto-resistance exhibits a series of clear oscillations which simulations reveal to be associated wit

We study quantum interference effects which are observed in the low temperature magnetoresistance of corrugated-gate wires fabricated in the GaAs/AlGaAs modulation-doped heterostructure system. Negative magnetoresistance, which appears over a large r

We study the magnetic field dependence of the correlation field ΔB c and amplitude δg of the conductance fluctuations, observed in the low-temperature magnetoresistance of a quasi-ballistic split-gate wire. With increasing the fields, there exists

We study carrier scattering processes in GaAs/AlGaAs quantum wires by a correlation field analysis of the conductance fluctuations observed in their low temperature magnetoresistance. In the diffusive transport regime, the magneto-resistance at low m

Zinc oxide (ZnO) nanowires (NWs) are grown on fluorine-doped tin oxide (FTO) glass substrates via a simple reactive evaporation method without the presence of any catalysts or additives. The ZnO NWs show high crystallinity and preferential elongation
