A study of intersubband infrared absorption in modulation doped p-type \(\mathrm{Si} / \mathrm{SiGe}\) quantum wells is presented for SiGe wells with thicknesses between \(22 \AA\) and \(64 \AA\) and \(\mathrm{Ge}\) contents in the range from \(23 \%\) to \(58 \%\). The peak positions of the absorpt
