Zheng, Z. Dai, Y. Dong, Y. Zhang, Y. Ma, H. Zhang, G. Li] Systematical studies of resistivity ρ(T), thermopower S(T), and thermal conduction κ(T) have been performed on the electron-doped manganites La0.9Te0.1Mn1−x Cr(Al) x O3 (0.05≤x≤0.20). The Cr005 and Al005 samples exhibit an insulator-metal transition in the ρ(T) curves, however, other samples present insulating behaviors in the whole measured temperature. The S(T) data increases with decreasing temperature and develop a peak at $T_{S}^{P}$ for all samples, with decreasing temperature further, another characteristic temperature $T_{s}^{m}$ is observed. The fits of ρ(T) and S(T) data in the high temperature region are presented, and the result shows that the electron conduction is governed by the VRH mechanism for Al-doped samples and the SPC mechanism for Cr-doped ones. As to thermal conduction κ(T), it is suggested that it comes from two sides, one is the phonon-phonon scattering due to disorder and the other is the spin-phonon interaction.
