摘要： A light emitter device (100) comprises a substrate (10) and a photonic crystal (20), which is arranged on the substrate (10) and comprises pillar- and/or wall-shaped semiconductor elements (21), which are arranged periodically standing out from the substrate (10), wherein the photonic crystal (20) forms a resonator, in which the semiconductor elements (21) are arranged in a first resonator section (22) with a first period (d1), in a second resonator section (23) with a second period (d2) and in a third resonator section (24) with a third period (d3), wherein on the substrate (10) the second resonator section (23) and the third resonator section (24) are arranged on two mutually opposing sides of the first resonator section (22) and the second period (d2) and the third period (d3) differ from the first period (d1), the first resonator section (22) forms a light-emitting medium and the third resonator section (24) forms a coupling-out region, through which a part of the light field in the first resonator section (22) can be coupled out of the resonator in a light outcoupling direction parallel to a substrate surface (11) of the substrate (10). Methods for operating and producing the light emitter device (100) are also described.

摘要： Described is a method for producing a semiconductor device (100), in which at least one column-shaped or wall-shaped semiconductor device (10, 20) extending in a main direction (z) is formed on a substrate (30), wherein at least two sections (11, 13, 21, 23) of a first crystal type and one section (12, 22) of a second crystal type therebetween are formed in an active region (40), each section with a respective predetermined height (h1, h2), wherein the first and second crystal types have different lattice constants and each of the sections of the first crystal type has a lattice strain which depends on the lattice constants in the section of the second crystal type. According to the invention, at least a height (h2) of the section (12, 22) of the second crystal type and a lateral thickness (D) of the active region (40) is formed perpendicular to the main direction, in such a manner that the lattice strain in one of the sections (11) of the first crystal type also depends on the lattice constants in the other section (13) of the first crystal type. A semiconductor device (100) is also described, having at least one column-shaped or wall-shaped semiconductor element (10, 20) on a substrate (30), which can be produced in particular by means of the stated method.
