摘要:
We have observed that the absorption spectra in bulk Fe‐doped indium phosphide differ considerably from those recorded on undoped andn‐type samples. In the former case it was seen that the absorption edge presents a tail whose shape depends on the concentration of iron atoms incorporated into the matrix. Based on this phenomenon, we present a new nondestructive method which can be successfully employed to measure the iron concentration in semi‐insulating InP.
