The resonances at microwave frequencies can be observed in polarized junctions; this was studied in previous papers and we have called for an important contribution of minority carriers. With a magnetic field B, a non diagonal component of the electr

The electrical susceptibility of the Silicon-electrolyte interface has been studied when the electrical irradiation field is parallel to the junction. In the High Frequency (H.F.) range, the absorption exhibits one maximum depending on the voltage ap

We measure the piezoelectric (d=65.10−12 m V−1) and pyroelectric (P=2,5 10−6 Cb m−2 °K−1) properties of K2 V3 O8. We try to obtain a coherence between these results, using the structure of K2 V3 O8 previously determined.

The resonances observed in polarized junctions induce one current that can be detected. With a magnetic field, one can observe the nondiagonal component of the electrical conductivity, a sort of microwave Hall effect. It is also possible to perform a

To verify some of the hypotheses used in previous papers (F. Blanc et al. Can. J. Phys. 66, 11 (1988); F. Blanc et al. Can. J. Phys. 67, 148 (1989); A. Gire et al. 68, 190 (1990)), we experimented with cyclotron resonance in polarized junctions. The

When an alternating electric field is applied parallel to a junction, the radiofrequency susceptibility gives an absorption having a maximum versus the direct current polarization of the junction; the real part of the susceptibility is negative. The

On mesure les sections de collision des couples HCHO — CO 2 et HCHO — NH 3 .On utilise pour cela un spectrometre a jet moleculaire de formol de type Rabi et on etudie l’intensite du jet de formol en fonction de la pression d’un gaz contenu da
