Hydrogen absorption and diffusivity in ZnO single crystals

Popis výsledku v původním jazyce

ZnO single crystals electrochemically charged with hydrogen were characterized. The concentration of hydrogen introduced into the crystals was determined by nuclear reaction analysis and was found to be in a reasonable agreement with the value estimatedfrom the Faraday's law. Moreover, a sub-surface layer with very high concentration of hydrogen and very high density of open-volume defects was formed by plastic deformation caused by hydrogen-induced stress. Specific surface modification caused by hydrogen-induced slip in the c-direction was observed on hydrogen loaded crystals. Hydrogen diffusion coefficient in ZnO was estimated by in situ electrical resistivity measurement. It was found that hydrogen diffusion in the c-direction is faster than in thea-direction most probably due to open channels existing in the wurtzite structure along the c-axis.
