Silicon Germanium Alloys

ABSTRACTA model is presented for the high temperature transport properties of large grain size, heavily doped p-type silicon-germanium alloys. Good agreement with experiment (±10%) is found by considering acoustic phonon and ionized impurity scattering for holes and phonon-phonon, point defect and hole-phonon scattering for phonons. Phonon scattering by holes is found to be substantially weaker than phonon scattering by electrons, which accounts for the larger thermal conductivity values of ptype silicon-germanium alloys compared to similarly doped n-type silicongermanium alloys. The relatively weak scattering of long-wavelength phonons by holes raises the possibility that p-type silicon-germanium alloys may be improved for thermoelectric applications by the addition of an additional phonon scattering mechanism which is effective on intermediate and long-wavelength phonons. Calculations indicate improvements in the thermoelectric figure of merit up to 40% may be possible by incorporating several volume percent of 20 Å radius inclusions into p-type silicon-germanium alloys.

R. B. Fair et al. have analyzed original data on the effect of heavy, uniform background doping with As and B on the diffusivity of Sb in Si at 1000°–1200°C. Their analysis attributed a role to “electric fields” and led to the conclusion that, for n-type background doping, Sb diffusion is dominated by double-negatively charged vacancies with no contribution from V−. For p-type backgrounds they concluded that donor-acceptor pairing alone retards the diffusion. Here it is shown (1) that electric fields do not play a role in their experiments, (2) that the contribution of V− to Sb diffusion in an n-type background is not zero but is roughly equal to that of V= for n/ni = 10, and (3) that the retardation of Sb diffusion in p-type Si is due both to donor-acceptor pairing and, principally, to the elimination of the contributions of V− and V=.

Macropore Formation

Tuning the pore diameter of porous silicon (PS) is essential for some applications such as biosensing, where the pore size can filter the entrance of some analytes or increase its sensitivity. However, macropore (>50 nm) formation on p-type silicon is still poorly known due to the strong dependence on resistivity. Electrochemically etching heavily doped p-type silicon usually forms micropores (<5 nm), but it has been found that bigger sizes can be achieved by adding an organic solvent to the electrolyte. In this work, we present the results of using dimethylformamide (DMF), dimethylsulfoxide (DMSO), potassium hydroxide (KOH) and sodium hydroxide (NaOH) for macropore formation in p-type silicon with a resistivity between 0.001 and 0.02 Ω∙cm, achieving pore sizes from 5 to 100 nm.
