2015年5月15日 · Many crystal growth processes of high-temperature superconductor YBa 2 Cu 3 O 7−δ (Y123) and its rare-earth substituted series have been studied for device applications composed of superconducting thin films. The processes include, for example, pulsed laser deposition, vacuum evaporation, chemical vapor deposition and metal–organic deposition.

2024年2月1日 · Our study presents a promising design strategy for N-doped fused ring electron acceptors (Y123) with remarkable electronic and photovoltaic properties. The investigation of major electronic contributions and energy levels reveals their potential for efficient charge transfer upon photoexcitation.

2023年7月25日 · The organic solar cells (OSCs) are being developed with the goal of improving their photovoltaic capabilities. Here, utilizing computational methods, six new nonfullerene acceptors (NFA) comprising dyes (A1–A6) have been created by end-group alterations of the Y123 framework as a standard (R).

1991年12月1日 · We found that the charged model clusters relating to the structural units can not describe the real properties of the Y123 and Y124 superconductors, so we need to use the charge model clusters relating to the entire unit cell. The oxidation state of Cu in the layer of Y123 system is higher than the oxidation state of Cu in the layer of Y124 system.

This paper presents a design strategy, their efficient visible light converting optimizations offsets and dye anchorage utility as N-doped fused ring electron acceptors of organic dye Y123 in photovoltaic and optical devices. Five novel dyes (Y1–Y5) are investigated, identifying major electronic contributions.

INTRODUCTION Since YBa2Cu307(Y123) superconductor which has highest critical temperature at 93K was found in 1987 (Wu et al., 1987), many researchers have performed vigorously to improve its superconducting properties and the results have been applied to the fabrication of various film or bulk type superconductors.

The critical temperature of the bulk samples of Y123, Y358 and Y257 and Y211 composite were investigated by aid of the dc electrical resistivity measurements using

A fabrication technique for a single-domain Y123 crystal by top-seeded melt processing was developed using two step undercooling. At the first undercooling step, the Y123 nucleus was stabilized, and increased growth rate was intended at the second undercooling step.

2001年1月1日 · By using the knowledge accumulated during last decade about the relationship between the structural features and the superconducting properties we have attempted to design an improved Y123 material that would display an increased superconducting transition temperature, T c, and enhanced critical current, J c, and irreversibility fields, B irr.
