“…After hydrazine reduction, the absorbance peak has a red shift to 270 nm, which suggested that the electronic conjugation within graphene basal plane is restored. [2][3] The graphene nanosheets can be clearly seen in the TEM micrograph, wrinkles or folds on the nanosheets may be attributed to graphene's large aspect ratio. YBCO powder used as the precursor for producing nanoparticles in MAPLE were characterized.…”

-Matrix-assisted pulsed laser evaporation (MAPLE) process has demonstrated to deposit polymers with a contaminationfree fashion. Here, MAPLE process is applied to deposit yttrium barium copper oxide (YBCO) superconductor particles on graphene sheets. The microstructures and elemental composition of YBCO nanoparticle deposited on graphene sheet by the MAPLE process were studied as a function of the irradiation time (t). The amount of YBCO nanoparticles deposited on graphene is increased with increasing t. The average particle size of the spherical YBCO nanoparticles deposited on graphene sheets is decreased from 70±25 nm to 50 ± 15 nm when t increases from 0.5 hr to 2.0 hr. This study demonstrates that MAPLE is a suitable process for depositing superconductor nanoparticles on graphene sheets.

“…However, LZO film can act as a good barrier of oxygen diffusion [11]. Therefore, a composite buffer layer combined with LZO and REdoped CeO 2 film is necessary for preparation of a highperformance YBCO superconducting coated conductor.…”

“…Among the buffer layers mentioned above, CeO 2 and LZO are considered as good candidates due to their satisfactory chemical compatibility and a low lattice mismatch with YBCO film [11][12][13][14][15]. The lattice parameter of LZO with a pyrochlore structure is 10.79 Å , providing a low mismatch of 0.5 and 1.8 % with the YBCO film (a-axis and b-axis, respectively) as well as 7.6 % with the Ni-W substrate [16].…”

Gd-, Y-, and La-doped CeO 2 films (Gd 0.2-Ce 0.8 O 2 , Y 0.2 Ce 0.8 O 2 , and La 0.2 Ce 0.8 O 2 ) are prepared on Ni-W tapes and La 2 Zr 2 O 7 -buffered Ni-W tapes using solgel method. The films are characterized by X-ray diffraction and atomic force microscopy. Results indicate that Y 0.2 Ce 0.8 O 2 (YCO) film shows the better crystallinity and the surface quality compared with Gd 0.2 Ce 0.8 O 2 (GCO) and La 0.2 Ce 0.8 O 2 (LCO) films. The YCO buffer layer has good in-plane texture with purely c-oriented grains. The YCO films deposited on La 2 Zr 2 O 7 (LZO) also demonstrate the good texture and the perfect surface quality. YBCO films are prepared on the YCO/LZO and LCO/LZO composite buffer layers through the low fluorine solution route. The YBCO film deposited on the YCO/LZO buffer layer displays a high T c of 89.6 K with a low transition temperature width (DT = 0.45 K), and a J c value of 0.5 MA/cm 2 , which is superior to that deposited on LCO/LZO buffer layer. Graphical Abstract Gd-, Y-, and La-doped CeO 2 films (Gd 0.2 Ce 0.8 O 2 , Y 0.2 Ce 0.8 O 2 , and La 0.2 Ce 0.8 O 2 ) are prepared on Ni-W tapes through sol-gel method. GCO film has a coarse surface, and the YCO film has the best texture and surface quality. Y 0.2 Ce 0.8 O 2 /La 2 Zr 2 O 7 and La 0.2 Ce 0.8 O 2 / La 2 Zr 2 O 7 composite buffer layers are also prepared and compared. The surface quality of Y 0.2 Ce 0.8 O 2 /La 2 Zr 2 O 7 is superior to that of La 0.2 Ce 0.8 O 2 /La 2 Zr 2 O 7 composite buffer layer. High-T c YBCO films with sharp DT = 0.45 K and a J c value of 0.5 MA/cm 2 are successfully obtained on the Y 0.2 Ce 0.8 O 2 /La 2 Zr 2 O 7 film, which is superior to that on La 0.2 Ce 0.8 O 2 /La 2 Zr 2 O 7 buffer layer.

CeO 2 /La 2 Zr 2 O 7 composite buffer layers were deposited on Ni-W tapes using chemical solution method.YBa 2 Cu 3 O 7-x (YBCO) films were then deposited on the CeO 2 /La 2 Zr 2 O 7 composite buffer layers using a low-fluorine solution route. Effect of the annealing temperature and annealing atmosphere on the texture of the CeO 2 layers was investigated. It was found that CeO 2 film annealed at 1000°C under the atmosphere of N 2 containing of 5vol. %H 2 shows a high degree of c-orientation on La 2 Zr 2 O 7 (LZO) film. Effect of oxygen partial pressure on the properties of YBCO films deposited on the CeO 2 /LZO buffer layers was also investigated. The YBCO annealed under N 2 containing of 500ppm O 2 shows the optimal properties, with critical current density (J c ) of 1MA/cm 2 at 77K, 0T.
