Abstract:
A transistor comprises a stack of semiconductor materials including, in particular, a first sub-layer, carefully arranged and with a specific thickness, splitting the buffer layer into two portions and including a third material so that the difference in the piezoelectric and spontaneous polarisation coefficients between the material of the buffer layer and the third material induces, at a first interface between the first portion of the buffer layer and the first sub-layer, a first fixed surface electric charge generating an electrical field directed along the axis z so as to follow the two-dimensional gas to be contained in the channel.

Claim (Index 5):
The field-effect transistor as claimed in  claim 1 , wherein the buffer layer further comprises a second sublayer that is located between the first sublayer and the second portion of the buffer layer, the second sublayer comprising Al x2 Ga (1\u2212x2) N, and x 2  being lower than x+15%, a second fixed surface electric charge at the second interface formed between the first sublayer and the second sublayer being positive and lower, in absolute value, than the first fixed surface electric charge of the first interface.
