High-Current, Double-Sided REBCO Tapes by Advanced MOCVD

High Performance Double-sided Psa Tape Produced by Uv Irradiation

High DC current gain InGaP/GaAs HBTs grown by LP-MOCVD - Electronics Letters

16 complex vector channel responses and for each BTS and MS location, the histogram of PAS correlation bandwidth for the urban environments investigated is given in Fig. 3. For prh = 0.5, the median spatial correlation bandwidth is 5MHz and for a small number of cases PAS correlation bandwidths of greater than lOMHz have been reached. For pth = 0.9 the the median spatial correlation bandwidth i...

High critical current density and low anisotropy in textured Sr1−xKxFe2As2 tapes for high field applications

From the application point of view, large critical current densities J(c) (H) for superconducting wires are required, preferably for magnetic fields higher than 5 T. Here we show that strong c-axis textured Sr(1-x)K(x)Fe(2)As(2) tapes with nearly isotropic transport J(c) were fabricated by an ex-situ powder-in-tube (PIT) process. At 4.2 K, the J(c) values show extremely weak magnetic field depe...

High Quality YBa2Cu3O7-x Superconducting Thin Films Grown by MOCVD

YBCO thin films have been grown by Metal Organic Chemical Vapour Deposition in ;I cold wall type reactor. The 0-diketonates of yttrium, barium and copper are used as precursors. Filrna have bcen deposited on (001 I MgO and (012) LaA103 single crystalline substrates. The morphology is very dependant on thc gas p h a x composition. Different oxygen partial pressures have been investigated. An inc...

Double-Sided Junctions Enable High-Performance Colloidal-Quantum-Dot Photovoltaics.

The latest advances in colloidal-quantum-dot material processing are combined with a double-sided junction architecture, which is done by efficiently incorporating indium ions in the ZnO eletrode. This platform allows the collection of all photogenerated carriers even at the maximum power point. The increased depletion width in the device facilitates full carrier collection, leading to a record...
