Association of FeB Pairs under Illumination

Abstract:

It has been found that association of iron-boron (FeB) pairs takes place during illumination of iron contaminated boron-doped silicon. The established FeB pair model is interpreted with respect to the quasi-Fermi level position, the stability condition of FeB pairs and the steady state reaction between interstitial iron, electrons and boron. At an excess charge carrier density of Δn = 5.4·10¹⁴ cm^-3, still 5 % of the interstitial iron associates to FeB pairs.
