Zusammenfassung
In crystalline silicon, atomic hydrogen released from hydrogen dimers forms acceptor-hydrogen pairs during annealing in the dark at elevated temperatures. In this study the formation of boron-hydrogen (BH) and gallium-hydrogen (GaH) pairs in 1 cm silicon is investigated at temperatures ranging from 140 to 220°C. Acceptor-hydrogen concentrations in the low 1014cm−3 range are quantified by means of highly sensitive resistance measurements. GaH pairs are generally found to form faster than BH pairs. Arrhenius analysis shows a difference in activation energy (BH: 1.20eV, GaH: 1.04eV) while the trial frequency is the same (∼4×108s−1).
