Elektroliza kroz homogene i nehomogene spojeve izolatora

The basic measurement of the primary state of ionization related to the formation of a non-rectifying contact by the electrolysis of insulating solids under homogeneous and heterogeneous contacts has been carried out. The activation energy involved in the first stage has been found to correlate with the band scheme of energy of contact which is necessary for creating the defect centres towards space charge limited injection.Načinili smo osnovna mjerenja početnog stanja ionizacije pri uspostavljanju neispravljačkog spoja nastalog elektrolizom na dodiru istorodnih ili neistorodnih izolatora. Našli smo da je prvotna aktivacijska energija vezana sa shemom pojaseva energijskih vrpci spoja koji su potrebni za stvaranje defektnih središta blizu ograničene injekcije prostornog naboja

Kinetička svojstva F-centara pod utjecajem topline

The migration of colour clouds after the electron injection in pure and doped KCl and KBr alkali halides under thermal and field stresses is studied with an anode contact of spherical geometry. The diffusion coefficient of the colour clouds has been obtained using a derived analytical expression and the experimental data, and the activation energy of the colour centre was estimated. The dissociation energy values under thermal and field stresses for doped crystals are deduced through the mobility transport equation. The results indicate the effect of doping in an otherwise pure counterpart of the same crystals.Proučavamo premještanje oblaka boje nakon ubacivanja elektrona u čiste i punjene kristale alkalnih halida KCl i KBr, pod djelovanjem topline i električnog polja, uz primjenu kuglaste elektrode. Pomoću izvedene analitičke relacije i mjernih podataka odredili smo koeficijent difuzije oblaka boje i ocijenili aktivacijsku energiju centara boje. Primjenom jednadžbe pokretljivosti izveli smo vrijednosti disocijacijske energije pod toplinskim i električnim naprezanjem za punjene kristale. Podaci pokazuju učinak punjenja u odnosu na čiste kristale
