Imaging of the interstitial iron concentration in crystalline silicon by measuring the dissociation rate of iron-boron pairs

Herlufsen, Sandra; MacDonald, Daniel; Bothe, Karsten; Schmidt, Jan


We present a dynamic approach for measuring the interstitial iron concentration in boron-doped crystalline silicon using photoluminescence (PL) imaging. This camera-based technique utilizes the characteristic dependence of the dissociation rate of iron-boron pairs on the interstitial iron concentration. We determine the dissociation rate by measuring the time-dependent PL signal after complete association of iron-boron pairs in the sample. Since we are only interested in the time dependence of...[Show more]
