Strongly correlated electron systems, especially the perovskite oxides with the general formula ABO3, have been studied for some decades due to their intriguing properties such as magnetism, mutiferroicity, ferroelectricity, colossal magnetoresistence and superconductivity [1]. In light of the previous studies of ABO3, A-site and B-site doping in these systems can lead to different crystal structures,...
The effect of introducing impurities in CdTe, namely antimony (Sb) and oxygen (O), on the net carrier concentration in CdS/CdTe solar cells and on their open-circuit voltage (V OC ) has been investigated. Oxygen was introduced in the CdTe films during the deposition of this layer by the close-spaced sublimation process. The total pressure was held constant at 1330 Pa (N 2 and O ...
The Na-doped p-type ZnO thin films were prepared by DC reactive magnetron sputtering. Two types of substrates were used for separate testing purposes: silicon wafers for crystallinity measurements and glass slides for electrical and optical transmittance measurements. The lowest room-temperature resistivity under the optimal condition was 59.9 Ω cm, with a Hall mobility of 0.406 cm2 V−1s−1 and a carrier...
