Summary form only given. CdS is a promising material for flat panel displays, light-emitting diodes, lasers, logic gates, and transistors. CdS has attracted special interest because it exhibits high photosensitivity and its band gap energy (2.41 eV) and electron affinity (4.5 eV) appear in the visible spectrum [1]. In this work, CdS deposition on surface of the vertical aligned carbon nanotube (VACNT)...
Summary form only given.Recently, there is an increased interest in quantum dot sensitized solar cell (QDSSC), i.e., applying semiconductor quantum dots (QDs) in dye-sensitized solar cells [1]. However, QDSSCs have shown comparatively lower efficiencies than expected. One possible reason for the poor efficiency of QDSSC is the difficulty of assembling the QDs on ZnO surface to obtain a well-covered...
CeO2 triangular microplates were obtained via thermal treatment of triangular precursor, which were synthesised through a convenient precipitation route using Ce(NO3)3??6H2O as the cerium source and NH4NO3 as the mineralising agent. The field emission scanning electron microscopy (FESEM) images show the obtained uniform trigon-like particles with edge lengths ranging from 2 to 5 um. The optical absorption...
Lead-free piezoelectric ceramics 0.96(K0.5Na0.5)(Nb0.96Sb0.04)-0.04LiTaO3 (96KNNS-4LT) have been prepared by using the conventional technique. The effect of the sintering temperature on the piezoelectric properties of 96KNNS-4LT ceramics was studied. The X-ray diffraction (XRD) and scanning electron microscope (SEM) show that all the ceramics possess a pure perovskite phase and dense microstructure...
