The longitudinal acoustic velocity for 1 GHz waves propagating along the 100 direction in p(++) porous silicon layers has been measured using an acoustic wave transmission technique. The velocities obtained are significantly higher than those previously observed for p(+) samples. The porosity dependence is measured to be V-L = 8.43 (1 - P)(0.58) km/s, where V-L is longitudinal velocity and P is porosity. The low value of the exponent (0.58) is an indication of a relatively well-ordered pore structure.
