Angular dispersion effects in the acoustoelectric interaction in ZnO and CdS

Ole Keller¹

Abstract: A theoretical investigation of the wave dispersion effects in the acoustoelectric interaction in ZnO and CdS has been made. The contributions to the velocity dispersion and the angular dispersion from acoustoelectric and elastic anisotropy are discussed. In particular, the acoustoelectric angular dispersion of the quasi‐transverse (T2) mode and the quasilongitudinal (L) mode for different acoustic frequencies has been studied. Surprisingly, it is found that the acoustoelectric angular dispersion is comparable … Show more

The frequency down‐shift in piezoelectric semiconductors due to spontaneous parametric amplification of sound waves has already been studied in different materials by Brillouin effect inside the high field domains, in particular in the growth of acoustic flux intensity. In this contribution, experimental results are given which prove the existence of an acoustoelectric current frequency change in photoconducting CdS apart from the presence of highfield domains crossing the sample. This change is equally due to a parametric exchange mechanism but is accompanied by a reduction of the acoustoelectric current which characterises this phenomenon. This behaviour in the amplification shall be studied following the crystallographic axis and at the same time in that off‐axis.

Electrochemical study of the activating solution for electroless plating of polymers

et al. 2007

This paper presents an electrochemical study about the activating solutions of the electroless plating of polymers, containing Pd(II), Sn(II) and Sn(IV) mixtures in HCl as main components. The objective of the study is the voltammetric characterization of these solutions by cyclic and linear voltammetry in order to study the recovery of tin and palladium from these solutions. The effect of concentration and rotation rate on the currentÀpotential curves was studied using the RDE technique. The electrochemical behaviour of solutions prepared in the laboratory was performed as a prior step to the further study of real activating rinsing solutions. The electrochemical reduction of Pd(II) takes place in two one-electron transfer steps which are mass transport controlled. The electrochemical reduction of Sn(II) and Sn(IV) is also mass transport controlled and takes place with direct formation of metallic tin, although the electrochemical reduction of Sn(IV) only takes place in solutions with HCl concentrations higher than 1 M. The presence of additives in the real solutions prevent the chemical reduction of Pd(II) and the formation of Sn(IV) hydroxylated complexes. This causes the appearance of well defined diffusion waves attributable to the electrochemical reduction of Pd(II) and Sn(IV). Hence, the recovery of both species simultaneously as well as separately could be carried out, if appropriate conditions are selected.
