Y transistor

The Y transistor belongs to the group of coherent semiconductor components . The electrons from the source enter one of the two Y-branches, whereby the current through the side gates is controlled in push-pull mode.

properties

The advantage over a conventional transistor is that in the area of ballistic transport, a barrier does not have to be built in any of the branches in order to conduct the electrons into the other branch. This is done by changing the direction of the electron wave function , so that the probability of the electrons flowing into one of the two branches is increased compared to the other. Switching is therefore not limited by the temperature.

The technology is based on a two-dimensional electron gas of a modulation-doped heterostructure with very high mobility. It is manufactured using electron beam lithography and a lift-off process .
