It is well known that nonequilibrium populations of phonons can be generated in bulk semiconductors by the relaxation of photoexcited hot electrons. In this paper we demonstrate that nonequilibrium phonons can also be generated in quantum wells by picosecond lasers and then probed by time-resolved R

The influence of ionic concentration of pore solution and matrix porosity on high frequency resistance (HFR) of hydrated cement paste were carefully studied. A new relation between HFR and porosity has been derived and its validity demonstrated by a series of experiments. A better description of the
