a sample of silicon is doped with 10 17

Doping (semiconductor) Wikipedia. The shallow thermal donors (STDs) in silicon doped with isotopic oxygen 16 O and 18 O have been investigated. The sample annealed at 1275°C for 4 h in a nitrogen ambient was measured by a Fourier transform infrared (FTIR) spectrometer at 10 K., and B is relatively large. In previous measurements of Si doped with shallow donors at just-metallic concentrations [23], the conductivity at 2 K is much lower (about 10 (Ω·cm)–1) than the conductivity we observe. We thus conclude that sample A is metallic, whereas samples C and D are insulating; sample B appears to be near the transition.
