A tunable plasmon resonator, comprising a plasmon resonance layer made of graphene, a crystalline group-IV-semiconductor material or a crystalline group-III-V semiconductor material, and arranged on a carrier substrate, the plasmon resonance layer having a plasmon resonance region that is exposed to a sensing volume and a tuning device that is integrated into the plasmon resonator and arranged and configured to modify a density of free charge carriers in the plasmon resonance region or to modify an effective mass amount of the free charge carriers in the plasmon resonance region by applying of a control voltage to tuning control electrode(s) of the tuning device, thereby setting a plasmon frequency of plasmon polaritons in the plasmon resonance region to a desired plasmon frequency value within a plasmon frequency tuning interval, for resonance excitation of plasmon polaritons by incident electromagnetic waves of a frequency corresponding to the set plasmon frequency value.

A semiconductor light emitter device, comprising a substrate, an active layer made of Germanium, which is configured to emit light under application of an operating voltage to the semiconductor light emitter device, wherein a gap is arranged on the substrate, which extends between two bridgeposts laterally spaced from each other, the active layer is arranged on the bridgeposts and bridges the gap, and wherein the semiconductor light emitter device comprises a stressor layer, which induces a tensile strain in the active layer above the gap.

A contact unit described includes a contact plate and a connection plugfor an adjusting device. A position sensor is disposed on the contact plate whose electrical contact results over conductor tracksmolded into the contact plate. The contact platefurther includes contact flagsfor contacting an electromotor, wherein the contact flagsare led outside to a plugover conductor tracks that are injected into the contact plate. All conductor tracks are led in a fixed position with respect to one another in a plug inner portion, wherein this plug inner portion is produced in one injection process with the contact plate, and connection between the contact plateand the plug inner portion results only through the conductor tracks

A spring assembly in a throttle valve connection for control of combustion air to an internal combustion engine, in which a rotor is movable in opposite directions to control flow of combustion air. The spring assembly has a coil spring with first and second legs at respective opposite ends engaging housing and rotor parts. The housing and rotor parts are provided with respective oblique surfaces engaging one of the legs of the spring when the spring is relaxed to resist relative rotation of the housing and rotor.
