Abstract
| Formation, structure, and stability of hydrogen correlated complexes, created at Cd acceptors in GaP, InP, and InAs have been studied after plasma charging as well as after H+ and/or He+ implantation at different energies. The different complexes were monitored by the perturbed angular correlation technique (PAC). In InP and Gap, the stability of Cd-H pairs is very similar for comparable Cd concentrations (ED = 1.4(2) eV and ED = 1.5(1) eV). In InAs, two different hydrogen correlated configurations are observed, one could be identified as Cd-H pair, oriented in 〈111〉 lattice direction (νQ = 427 MHz, η = 0). The second complex involves at least one H atom and radiation defects or, favoured by a defect induced, secondary mechanism several hydrogen atoms. |
