Superimposed boundary1/8/2024 ![]() Institute of Electrical and Electronics Engineers, Fujiwara, in Proceedings of 29th IEEE Photovoltaic Specialists Conference ( A comparison of μ opt with μ H clarified the effects of the mixed approach not only on the reduction of the grain boundary contribution to the carrier transport but also on retaining high carrier mobility of in-grains for the AZO films. From the analysis of optical data based on the simple Drude model combined with the Tauc-Lorentz model and the results of Hall effect measurements, the optical mobility ( μ opt) was determined. AZO films were deposited on heated non-alkaline glass substrates (200 ☌) using ZnO:Al 2O 3 (2 wt. % Al 2O 3) ceramic oxide targets with the total power varied from 150 to 300 W, and at various RF to DC power ratios, AZO films deposited by a mixed approach with the RF to the total power ratio of 0.14 showed the lowest resistivity of 2.47 × 10 −4 Ω cm with the highest carrier concentration of 6.88 × 10 20 cm −3 and the highest Hall mobility ( μ H) of 36.8 cm 2/Vs together with the maximum value of an average transmittance in the visible spectral range from 400 to 700 nm. The ultimate drift ratios of all specimens are greater than 1/70, which satisfy the design requirement of deformation capacity of reinforced concrete shear walls under rare earthquake level.The effects of using radio-frequency (RF)-superimposed direct-current (DC) magnetron sputtering deposition on the structural, electrical, and optical properties of aluminum-doped ZnO (AZO)-based highly transparent conducting oxide films have been examined. The drift ratio at peak load is about 1/80 and 1/140 for the specimens with and without increment of the overlapping reinforcement area, respectively. The peak load of the specimen with 33% increment of the overlapping reinforcement area increases about 12%. The moment resisting capacity of the specimens is about 1.06~1.21 times of the predicted value. The hysteretic curves of all specimens are quite plump but the curves of specimens with increment of the overlapping reinforcement area are plumper, the stiffness degradation is decreased and the energy consumption capacity is improved. The local deflection concentration and local damage near the bottom have been controlled significantly. Increasing the overlapping reinforcement can effectively shift the wall damage zone from the bottom horizontal joint to the top zone of the overlapping bars in the boundary elements. Two specimens with increment of the overlapping reinforcement area have more cracks and distribute more symmetrically and uniformly. The test results indicate that all specimens fail in flexural failure mode. The influences of axial force ratio, boundary element form and increment ratio of overlapping reinforcement area (0%, 25% and 33%) on specimens were analyzed. Three specimens included one specimen with confined boundary elements under axial force ratio of 0.2 and two specimens with construction boundary elements under axial force ratio of 0.1. To research the seismic performance of this wall, experimental study on seismic behavior of three DSWPBE full scale specimens with height to depth ratio of 2.0 under lower axial force ratio was conducted. Regarding its local deflection concentration near the bottom seam, a double-superimposed shear wall with appropriate increment ratio on overlapping reinforcement area was designed. Double-superimposed shear wall with prefabricated boundary elements (DSWPBE) is an assembled shear wall with high precast ratio.
