Abstract

Hydrogen effusion measurements reveal that the total hydrogen concentration in ZnO ranges from 5.2×1016 cm−3 for single crystal ZnO to 3×1021 cm−3 for polycrystalline ZnO thin-fims. From the H effusion spectra the hydrogen chemical potential is determined as a function of the H concentration that can be related th the H density-of-states distribution. Single crystal ZnO exhibiting the lowest H concentration reveals six peaks in the H density-of-states located between 0.59 and 1.4 eV below the H transport site. With increasing H concentration the amount of H accommodated with binding energies larger than 1.0 eV increases significantly.
