摘要： A process for the production of contacts for electrically operated II/VI semiconductor structures (for example laser diodes). The contact materials palladium and gold hitherto used in relation to electrically operated II/VI semiconductor lasers are distinguished by a relatively great, not purely ohmic specific contact resistance in relation to the II/VI cover layer. The consequentially necessary higher operating voltages result in the unnecessary generation of heat and thus substantially accelerate degradation of the entire laser structure. That effect causes a limitation in terms of the service life of II/VI semiconductor laser diodes. The invention permits the operation of semiconductor laser diodes with lower operating voltages. The II/VI semiconductor laser diodes produced with our invention are distinguished by a longer service life. That permits inter alia commercial use of semiconductor laser diodes in the blue-green spectral range.
摘要翻译：用于生产用于电操作的II / VI半导体结构（例如激光二极管）的触点的方法。迄今用于电操作的II / VI半导体激光器的接触材料钯和金的特征在于相对于II / VI覆盖层相对较大而非纯欧姆的比接触电阻。因此必要的较高工作电压导致不必要的热量产生，从而基本上加速整个激光器结构的劣化。这种影响导致了II / VI半导体激光二极管的使用寿命方面的限制。本发明允许具有较低工作电压的半导体激光二极管的操作。本发明生产的II / VI半导体激光二极管具有较长的使用寿命。这允许在蓝 - 绿光谱范围内商业使用半导体激光二极管。

摘要： The invention relates to a method for operating a cooling system, in which a cooling agent is prepared in a reservoir of an evaporator device (1) of a single- or multi-stage sorption cooling system, a fluid to be cooled is cooled by having a heat exchanger of the evaporator device (1) effect a cooling heat transfer from the fluid to be cooled to the cooling agent for cooling purposes, and the cooling heat transfer causes the cooling agent to at least partially evaporate on the heat exchanger, and the evaporated cooling agent is relayed to a liquefier device (2), wherein the cooling heat transfer is improved by conveying external thermal energy provided by an external heat source (10) to the cooling agent, specifically in addition to and separately from the cooling heat transfer, and thereby initiating bubble formation that supports cooling heat transfer in the cooling agent in the reservoir, specifically by inducing bubble formation in conjunction with supplying the external thermal energy or intensifying bubble formation triggered by the cooling heat transfer. In addition, the invention relates to a cooling system in single- or multi-state configuration.

摘要： A charge measuring device detects focused ion beam attacks on an integrated semiconductor circuit with a capacitor, a field effect transistor, and a charge collecting device all manufactured in the integrated semiconductor circuit and insulated from additional circuit elements. A first pole of the capacitor is conductively connected to the charge collecting device and a gate of the field effect transistor. When a voltage is applied to the second pole of the capacitor, a drain source current flows through the field effect transistor, and a relationship between the voltage and the drain source current is ascertained. A comparison of the relationship with a previously ascertained relationship indicates a change of the charge quantity stored in the capacitor by the charge collecting device.

摘要： An apparatus and a method for determining an antenna characteristic of an antenna under test in free space is disclosed. Measurement results of a transmitted power of a measurement signal transmitted between the reference antenna and an antenna under test are detected, wherein detecting takes place in the frequency domain. The detected measurement results are transformed into the time domain and a time-domain filter is applied to the measurement results converted into the time domain. A filter width of the time-domain filter is determined in dependence on a spatial distance between the reference antenna and the antenna under test. Measurement result portions that result due to a multipath propagation of the measurement signal between the reference antenna and the antenna under test are reduced or removed.

摘要： An injection modulator for modulation of optical radiation, having an optical waveguide and a diode structure, having at least two p-doped semiconductor portions, at least two n-doped semiconductor portions and at least one lightly or undoped intermediate portion between the p-doped and n-doped portions. The p-doped portions when viewed in the longitudinal direction of the waveguide are offset with respect to the n-doped portions and the diode structure is arranged in a resonance-free portion of the waveguide. The p-doped portions lie on one side of the waveguide, the n-doped portions lie on the other side of the waveguide and the intermediate portion lies in the center, each portion extends transversely with respect to the waveguide longitudinal direction in the direction of the waveguide center of the waveguide and no p-doped portion when viewed in the longitudinal direction of the waveguide overlaps any n-doped portion.
