Phonon scattering in phosphorus-doped silicon has been studied using a heat-pulse technique in which backscattering is measured. With crystal sizes of the order of 10 mm and with phosphorus concentrations up to 1.8*10<sup>16</sup> cm<sup>-3</sup>, it has been shown that single-phonon scattering is predominant. A theoretical curve has been fitted to measurements of backscattered pulse amplitude as a function of input pulse power, and from this fit the authors have been able to deduce the constant A for isotopic Rayleigh scattering in pure silicon (A=0.43 s<sup>-1</sup> K<sup>-4</sup>), the deformation potential E<sub>u</sub> associated with the bottom of the conduction band (E<sub>u</sub>=8.6 eV), and the Bohr radius r<sub>0</sub> of the phosphorus impurity (r<sub>0</sub>=16 AA). These results are in agreement with those derived by other workers from thermal conductivity measurements. |
