| Abstract: | The present work is a pioneer study of the capture centres of charge carriers in yttriumaluminium borate crystals. An evaluation was made for the activation energies of the trapping centres and their frequency factors. The highest thermally stable trapping centres were shown to be characterized not so much by relatively high activation energy values, but rather high frequency factors exceeding the values of the natural frequencies of atom oscillations. On the basis of experimental results, models were suggested for some electron capture centres to reveal donor elements. |
