The electrical and thermoelectric properties of Ag2Te containing excess Ag (0.25 at. %) were studied. At 0.1–0.12 at. % excess Ag, Ag2Te undergoes an electronic phase transition attributable to the formation of a new Ag sublattice. 相似文献

A passive matrix electrochromic display (ECD) working in transparent or reflective mode is described. In this paper, we report the main reasons of image diffusion and cross-talk in passive matrix ECD and initial computer simulation results of the 7×7 matrix display. These suggest that the insulation of electrolyte under each pixel and threshold (nonlinearity) of coloration current can in practice completely eliminate the image diffusion and cross-talk. The matrix addressed ECD based on solid polymer electrolyte and two complementary electrodes, (WO3+0.1TiO2, TiO2–0.25CeO2), in which all pixels were insulated by negative photoresist material was elaborated. An additional protected thin film (0.2Li2O–0.2CeO2–0.6SiO2) deposited on working electrode was used to provide the enhanced threshold effect. The ECD exhibited excellent memory effect and substantially free from image diffusion and cross talk effects. 相似文献

The conductivity σ, Hall coefficient R, and thermoelectric power α0 of p-Ag2Te were studied in the temperature range of 300–550 K. Inconsistency between the signs of R and α0 was observed at 420–550 K. These results are interpreted within the two-phase model with spherical constant energy surfaces. It is established that the inconsistency between the R and α0 signs is due to the emergence of the scattering mechanisms with the parameters r0ac, r00, and r0d an increase of about 50% in the ratio of the effective electron and hole masses as a result of the transition α → β. 相似文献

A single-crystal sample of gadolinium ferrite garnet Gd3Fe5O12 was studied by Mössbauer spectroscopy near compensation point T cm (T cm = 286 K). The relative intensities of absorption lines in 57Fe Mössbauer spectra allow it to be concluded that the domain sizes in ferrite grow with the temperature approaching T cm, with domain structure in the sample disappearing at compensation point T cm. 相似文献

It is necessary to welcome the publication of the paper by Park and Bongiorno Jr (Park, K. and Bongiorno Jr, J.J. (2009), ‘Persistent Inputs and the Standard H2-multivariable Control Problem’, International Journal of Control, 82, 2002–2012) in which the special cases in H2-optimisation problems are considered. However, for correct orientation of readers we would like to note some publications which, in our opinion, are connected to a problem given by Park and Bongiorno Jr (2009), but are absent there. 相似文献
