First, a non-negative tensor factorization algorithm is improved by imposing sparseness constraints on it. Secondly, the bispectral images of mechanical signals are obtained and stacked to form a third-order tensor. Thirdly, the improved algorithm is used to extract features, which are represented by a series of basis images from this tensor. Finally, coefficients indicating these basis images' weights in constituting original bispectral images are calculated for fault classification.

XRD results indicate that the major diffraction peaks of the film match those of Sb2Te3. The film growth is apparently at the ［101］/［012］ orientation and many Te peaks are observed. Hall measurement reveals that all the samples are p-type and the resistivities are low. The electric conductivity of the films approaches that of the bulk metal and the carrier concentration is of 1023 cm-3. Seebeck coefficient measurement shows that the samples have nice thermoelectrical properties and the seebeck coefficients are in the range of 7.8—62 μV/K. Among all, the samples annealed at 200 ℃ for 6 h have the highest seebeck coefficient of about 62 μV/K and the lowest resistivity.
