    Abstract. An interaction between an acoustic wave and free carriers in interface region of semiconductor structures has been proved to be an effective tool for the experimental investigation of deep centers. In high resistivity and along with photosensitive semiconductors the interface with space charge inhomogenity can be produced by the suitable non-uniform illumination of the sample with the weakly absorbed light. Applying a high frequency external electric field on interface region in proper conditions can then directly generate the longitudinal, transversal or surface acoustic wave. The time development of such generated acoustic wave amplitude is investigated to determine the deep centers parameters. The possibility to detect the deep centers by this way depends, however, on both the type and polarization of generated acoustic wave. In the contribution some experimental procedure is described and deep centers investigation for various generated acoustic waves in high resistivity GaAs sample are presented and compared.

    Abstract. A considerable interest is given in experimental study of glassy with the fast ion transport because they play an important role in a number of modern electrochemical devices, such as solid-state batteries, electrochronic displays, and sensors as well as for fundamental interest in their ion transport mechanisms. It is known that the investigation of electrical conductivity spectra of ionic glasses can reflect the basic features of the relaxation and transport mechanisms of the mobile ions. However, the transport mechanisms can be investigated also by acoustic methods, that can have some advantages comparing to electrical ones as the high sensitivity, absence of contact phenomena and so on In the contribution we present some acoustical properties of glasses prepared in the system Cu-CuBr-Cu2O-P2O5 containing Cu+ conductive ions. The ion transport mechanisms in these fast ion conductive glasses is investigated and the relation between acoustical and electrical properties considering the various glass compositions is determined. The both acoustical and electrical measurements are also utilized to the ion activation energy determination.

    Abstract. Acoustoelectric interaction in both semiconductor and semiconductor structure interface regions has been proved to be an effective tool for the experimental investigation of deep centers and two basic modifications of acoustic transient spectroscopy (A-DLTS) based on the acoustoelectric effect were developed. The longitudinal acoustic wave technique uses an acoustoelectric response signal observed at the interface when a hf longitudinal acoustic wave propagates through the structure. The surface acoustic wave (SAW) technique uses a nonlinear acoustoelectric interaction between the SAW electric field and free carriers in an interface region which generates a transverse acoustoelectric signal accros the stucture.

    Abstract. In recent years, the technological interest in fast ionic conductivity in solid materials is increased for various solid-state electrochemical devices. While many known crystalline materials with the ability of fast ion transport have the limiting factor of their application in the achievement of requested structural parameters ensuring the high ion conductivity, the ion conductive glasses have several advantages the most important of which are: the absence of grain boundaries, the isotropic properties and the composition variability easy preparation, their stability and the large available composition ranges. The acoustical methods have been proved an effective tool to study the fundamental structural and mechanical properties of the ionic materials and can also significantly contribute to find the fundamental experimental knowledge's about the mechanical properties of the new kinds of ion conductive glasses and determine their relationship with the electrical ones. In the present contribution we have presented acoustic facilities and illustrated the possible coherence between the acoustical and electrical properties of ion conductive glasses of the system CuI-Cu2O-(P2O5+M0O3).

    Abstract. The technological interest in fast ionic conductivity in solid materials is increased for various solid state electrochemical devices. Apart from some crystalline materials, the high ionic conductivity at room temperature has been observed in some ion conducting glasses. Comparing with the crystalline materials the ion conductive glasses have several advantages the most important of which are: the absence of grain boundaries, the isotropic properties and the composition variability. The acoustical methods have been already proved an effective tool to study the fundamental structural and mechanical properties of the ionic materials and can also significantly contribute to the fundamental experimental knowledge about the mechanical properties of the new kinds of ion conductive glasses and to the determination of their relationship with the electrical ones. In the present contribution we have illustrated the possible relation between the acoustical and electrical properties of ion conductive glasses of the system CuI-CuBr-Cu2O-(P2O5+MoO3) for different glass composition. The both acoustical and electrical measurements are also utilized to the study of relaxation processes occurring in these fast ion conductive glasses and to the ion activation energy determination.

    Abstract. The acoustical and electrical methods have been already proved to be an effective tool for studying the fundamental structural, mechanical and also transport of the ionic materials. Thus we can determine the relationship between mechanical and electrical properties of the new kinds of ion conductive glasses. In the contribution we present both the data obtained by electrical measurement ( and a.c. conductivity) and acoustical measurement (acoustical attenuation) of ion conductive glasses of the system CuI-CuBr-Cu2O-P2O5 for different glass composition and outline the possible relation between its acoustical and electrical properties. The expected mixed cation effect in the electrical conductivity and acoustical attenuation spectra of several systems of CuI-CuBr-Cu2O-P2O5 that differ by the concentration of its components ion conductivity glasses is identified and their interrelation is analyzed. We observe characteristic effects in frequency response of the complex electrical conductivity and in the magnitudes of acoustic attenuation.

    Abstract. The investigation of acoustic spectra in ion conductive glasses with different composition can reflect the basic features of the relaxation and transport processes of the mobile ions. It was found that the temperature responses of all acoustic spectra are very similar and the relaxation peaks associated with ion transport depend on the glass composition. Experimental and theoretical aspects of acoustic attenuation measurements in ion conductive glasses of the system CuI-CuBr-Cu2O-P2O5 are reviewed. Theoretical studies of acoustic spectra due to the ionic hopping motion and relaxation processes connected with the mobility of Cu+ conductive ions are compared with experimental results and some attempts to fit the acoustic attenuation spectra are accomplished.

    Abstract. The experimental study of transport mechanisms in glassy electrolytes with fast ion transport attracts the considerable interest for its important role in a number of modern electrochemical devices. Acoustical measurements can characterize different relaxation processes in the ion conductive glasses and seem to be a useful technique for nondestructive investigation of transport mechanisms in conductive glasses even with some advantages compared to the electrical measurements. The distinctive peaks of acoustic attenuation spectra which are caused by resonant interaction with the mobile ion hopping processes enable us then to study relaxation and transport mechanisms in the ion conductive glasses.
