摘要:

We report an experiment on acoustic surface wave storage in photoconducting CdS which leads to a decay time as long as 100 ms. Both charging and storing times are deduced from the experimental amplitude of the echo restored by a readout pulse. In addition we find that charging and discharging of the memory seem to obey a two‐step process.
