Abstract:
1. A semiconductor actuator, comprising: a substrate base; a bending structure connected to the substrate base and deflectable at least partially relative to the substrate base, the bending structure having semiconductor compounds of nitrides of main group III elements; and at least two electrical supply contacts which one of (a) impressing an electrical current in and (b) applying an electrical voltage to the bending structure, the at least two of the supply contacts being at least one of (a) disposed at a spacing from each other respectively on the bending structure and (b) integrated in the bending structure, wherein the bending structure is securely connected in selected portions to the substrate base, the bending structure being cantilevered and deflectable in further selected portions relative to the substrate base, wherein the bending structure has at least one of a homogeneous semiconductor layer and a semiconductor hetero structure, and wherein at least one of (a) the homogeneous semiconductor structure comprises or consists of one of GaN, InN and AlN and (b) the semiconductor heterostructure has a first structure made of one of GaN, InN and AlN and a second structure made of one of AlxGa1-xN, InxGa1-xN and InxAl1-xN.
