Our final target is to measure and research the acoustic current which is produced by that saw carry the electron passing through the quasi - 1d electron channel at the cut off voltage of the quasi - 1d electron channel , so as to research the quantum acoustic current steps of the quasi - 1d electron channel
2.
The emphases of our research works are as follows : under ultra - low temperature ( about 0 . 236k ) conditions , how the frequency and power of the saw and the source drain voltage influence the acoustic current ; and the relationship between the source drain current and the split - gate voltage ; and how to find the cut off voltage of the quasi - 1d electron channel ; and also the frequency character of the idt in the saw parts
