Abstract
The temperature dependence of hydrogen blistering rates are measured in (100) Si, (111) Si and (100) Ge substrates implanted with 40 keV H-ions to a fluence of 6 × 1016 H cm-2 using real-time imaging of samples during annealing. The time taken for blisters to form was found to exhibit Arrhenius behaviour and to be characterised by a single activation energy over the temperature range examined (375-650 °C for Si and 300-600 °C for Ge). The extracted activation energies, which are believed to be the sum of a hydrogen-complex (H-X) dissociation energy and a hydrogen migration energy, were found to be 2.28 ± 0.03 eV for (100) and (111) Si and 1.4 ± 0.03 eV for (100) Ge. These results are discussed with reference to a model for blister formation and compared with previously reported measurements. Crown
