Patent attributes
A device to produce an output based on interference of electron waves is disclosed. Said device comprised out of two areas having different medium properties for propagation of an electron wave, where the first of said areas is connected to a source to inject electrons and the second of said areas is connected to a drain to collect electrons while said electrons have a propagation path through the device starting at the source and ending at the drain. Said areas are designed in a manner to result in advancing and reflected waves having interleaved sections along said path which yield interference, either constructive or destructive, thus determining the transport probability of the electron through the device. Said device is operated either as a switch, in a first embodiment, by adding a control gate, or as a detector, in a second embodiment, used for measurement of external particle ensemble properties.
