Abstract
We report frequency dependent contrast in d(S11)/dV measurements of a variably doped p-type silicon sample in the frequency range from 2GHz to 18GHz. The measurements were conducted bys use of a scanning microwave microscope. The measurements were done at a selected frequency by varying the DC tip voltage. The measured d(S11)/dV signal shows maximum for doping concentrations of 10(u)15 (d)- 10(u)16(d)cm(up)03(d) at 2.3 GHz and this maximum sequentially shifts through the regions of increasing dopant concentration displaying maximum for concentrations of 10(u)17(d)-10(u)18(d)cm(up)-3(d) at 17.9 GHz.Citation
