摘要

测量了几种掺铁InP晶圆的磁光法拉第旋转。这些测量提供了单个Fe:InP孔中Fe浓度变化的信息。铁浓度随籽粒到籽尾距离的增加而增加。这一趋势得到了光学吸收光谱的验证，该光谱也被用来估计孔内铁浓度的净变化。低温光吸收光谱估计净铁浓度为1.124/spl倍/10/sup 17/ cm/sup -3/。然而，从我们的室温吸收光谱中得到的净Fe浓度为1.7/spl倍/10/sup / 17/ cm/sup -3/。最后，测量了Fe:InP晶体中法拉第旋转的色散。

Investigations of the Faraday effect in Fe-doped InP

The magneto-optical Faraday rotation was measured for several Fe doped InP wafers. These measurements provided information on the variations in Fe concentration across a single Fe:InP boule. The Fe concentration was observed to increase in the boule with distance from the seed to the tail. This trend was verified with optical absorption spectra, which were also used to estimate the net changes in Fe concentration within the boule. From low temperature optical absorption spectroscopy, the net Fe concentration was estimated to be 1.124/spl times/10/sup 17/ cm/sup -3/. However, the net Fe concentration derived from our room temperature absorption spectra was 1.7/spl times/10/sup 17/ cm/sup -3/ Finally, the dispersion of the Faraday rotation in the Fe:InP crystal was measured.
