L'effet photodiélectrique

Abstract: Sommaire.-L'effet photodiélectrique se présente comme une variation de la capacité et des pertes diélectriques d'un condensateur dont le diélectrique est une poudre phosphorescente cristalline, quand on irradie le phosphore avec des radiations susceptibles d'agir sur la phosphorescence des cristaux. Contrairement à ce qu'on a cru longtemps, la plupart des phosphores cristallins donnent lieu à cet effet. En général, la variation de capacité suit d'assez près la phosphorescence. L'ampleur de l'effet dépend beauc… Show more

“…According to the first, the photodielectric effect is due to thc photoconductivity: the carrier concentrations increase in the bands and this changes the dielectric losses. According to other investigators, the photodielectric effect is due to trapping : electrons are trapped at some sites in the crystal and form polarizable complexes giving rise to a dipolar Debye absorption [ 2 ] . These complexes having a high polarizability [3], the change in the dielectric constant can be very large even though a small amount of electrons is trapped.…”
