Abstract: The active layer (1) and the barrier layers (2) contain a group III component, a group V component and nitrogen, whereby the active layer is a quaternary material and the barrier layers are ternary materials, or, in order to match the lattice properties of the active layer to the barrier layers, the nitrogen content in the barrier layers is higher. The active layer is preferably InGaAsN, the barrier layers are InGaAsN with higher nitrogen content or GaAsN. Superlattices may exist in the barrier layers, for example, series of thin layers of InxGa1-xAsyN1-y with varying factors x and y, where, in particular, x=0 and y=1.

Abstract: DH-PHEMT on a GaAs substrate, with a mixed crystal composition that is varied in the channel in such a way that the lower boundary of the conduction band is lowered toward the gate contact, and advantages of an SH-PHEMT are thereby simultaneously realized. For this purpose, the channel is for example InGaAs, and the In portion x of the In.sub.x Ga.sub.1-x As of the channel is increased in a step from 0.2 to 0.3 in the direction toward the gate contact.
