Measured relaxation time of valley polarization rel in silicon ( a ) and diamond ( b ) compared with the intervalley scattering time obtained from the numerical solution of the Boltzmann transport equation using a Monte Carlo approach (solid curve). The experimental points represent the decay time obtained by fitting the experimental data for averaged over 20 temporal scans per point by a single-exponential decay function. The shaded regions represent the standard deviation of the exponential decay time obtained by fitting the measured dynamics of . The pre-excited electron density is N =1.8 10 17 cm 3 (black squares) and N =1.5 10 18 cm 3 (green circles) for the data in a and N =4.4 10 15 cm 3 (black squares) and N =6.4 10 16 cm 3 (green circles) for the data in b .
