“…A radiotracer technique has been also used in case : tritium (3H ) is introduced into p-type poly talline silicon (R.A.D. or Wacker) by catl polarization in acidic salt bath electrolyte at If labelled with tritiated water [11]. By photocu: measurement it is checked that a certain passiv of the recombinating centres is thus obtained High resolution autoradiographies (0.2 03BCm r ution) are exposed on the specimens either in bulk shape or as thin foils ready for transmit electron microscopy [13].…”

“…Their segregation to grain boundaries has been observed and it enhances the GB electrical activity. Rallon et al performed combined EBIC and autoradiography in the « ribbon-against-drop » (RAD) material (grown on a graphite film), they indeed found 14C segregation to GBs and twin boundaries, and showed that the latter have electrical activity linked with C presence [94]. Oxygen in other respects, has been detected at Si GBs by Kazmerski and Russel, by SIMS and AES, before and after annealing [84].…”

“…3.3 DiscussioN. -La passivation chimique par l'hydrogène des défauts recombinants d'interfaces ou de volume est en accord qualitatif avec les observations faites en autoradiographie à haute résolution sur lames minces préparées sur des échantillons initialement chargés en tritium à 150 OC par une méthode électrolytique [17]. Ces travaux avaient montré une ségrégation de tritium très importante le long des joints de grains et sur les dislocations extrinsèques dans les joints de mâcles 1:3 ; une ségrégation en amas avait été aussi observée dans le volume exempt de défauts étendus.…”
