Using first-principles calculation method, we have investigated the zone-center phonon modes, dielectric and transport properties of the LiNbO3-type CdPbO3. The results show that the relatively large peaks of infrared (IR) and Raman spectra mainly come from the [Formula: see text] and [Formula: see text] modes, respectively. The dielectric constant calculations reveal that this compound is positive uniaxial crystal and has the large dielectric constants. By investigating the electric transport properties using gold as electrode, the interesting negative differential resistance (NDR) effect can be observed, which reveals this compound should have important application in semiconducting electronic devices.

Based on MoC2 nanoribbons and poly-(terphenylene-butadiynylene) (PTB) molecules, we designed MoC2-PTB molecular spintronic devices and investigated their spin-dependent electron transport properties by using spin-polarized density functional theory and non-equilibrium Green's...

The electric resistivity, Seebeck coefficients and power factors of Y1-xEuxBaCo4O7+δ(x = 0.0, 0.05, 0.1, 0.2) ceramics were investigated from 400K to 1000K. The results show that the presence of Eu decreases electrical resistivity, and has little effect on Seebeck coefficients of the samples. The activation energy of conductivity is calculated by the Arrhenius plots in the semiconductive region. According to power factors, the optimum Eu substitution amount is x = 0.1, which results in a higher power factor of 67.5 μWm-1K-2at 1000K, 30% higher than unmodified sample YBaCo4O7+δ.
