During the formation of the plasma, a bias voltage is applied to the substrate. The method further includes depositing, on the cleaned surface, a subsequent layer.

The preparation method thus makes it possible to improve the quality of the interface between the layer with a basis of a III-V material and the subsequent layer. The electrical properties of the component are consequently improved.
