Abstract
An electronic component includes a substrate; a stack of two layers of different semiconductor materials, designed to form a layer of electron gas at the interface thereof or close to same; and a buried barrier forming a separation between the substrate and said stack. The buried barrier includes a first layer of a ternary alloy of semiconductor material of the III-N type, having an increasing concentration of one of the chemical species of the ternary alloy of the first layer the closer it is to the substrate; and a second layer of a ternary alloy of semiconductor material of the III-N type, formed beneath the first layer and having a decreasing concentration of one of the chemical species of the ternary alloy of the first layer the closer it is to the substrate.
