    摘要： A semiconductor radiation detector with layer-wise construction and a contive region having a two-dimensional or quasi one-dimensional electron or hole gas is provided in which adiabatic transport in edge channels occurs at least regionally and in which at least two contacts are provided to this conductive region. The transport in the edge channels is disturbed by interaction with the electromagnetic radiation to be detected, i.e. an increase of the scattering rate between the edge channels is caused. This leads to a change of the resistance measurable between the contacts, with a means being provided for measuring the change of resistance to thereby detect the incident radiation.

    摘要： The invention relates to an optical module, comprising a semiconductor element having a surface that is sensitive to electromagnetic radiation and an objective for projecting electromagnetic radiation onto the sensitive surface of the semiconductor element (image sensor or camera chip, in particular CCD or CMOS). The objective preferably comprises at least one lens and one lens retainer.In the optical module, an optical element having two sub-areas is arranged either in the space between the objective and the sensitive surface of the semiconductor element or between individual lenses of the objective in the entire cross-section of the beam path. All electromagnetic radiation that reaches the sensitive surface of the semiconductor element passes through the optical element.A first distance range (e.g. near range) is imaged in a first area of the sensitive surface of the semiconductor element in a focused manner by a first sub-area of the optical element, and a second distance range (e.g. far range) is imaged in a second area of the sensitive surface of the semiconductor element by a second sub-area.

    摘要： Polymer dispersions are prepared by reaction of a polyisocyanate and a hydroxylmethyl containing polyester polyol derived from a fatty acid to form a prepolymer, dispersing the prepolymer in an aqueous phase and then curing the prepolymer to form solid particle particles. The prepolymers can be prepared having isocyanate, hydroxyl, or a variety of other reactive functional groups. The dispersions are useful in a variety of coating, sealant, adhesive and elastomer applications.

    摘要： An MRAM cell includes a magnetic tunnel junction including first and second magnetic regions stacked in a parallel, overlying relationship and separated by a non-magnetic tunneling barrier layer. The first magnetic region includes a reference layer having a fixed magnetization adjacent the tunneling barrier layer. The second magnetic region includes a free layer having first and second free magnetizations aligned with an easy axis of magnetization of the free layer. The first and second free magnetizations are oppositely aligned and separated by a magnetic domain wall. The magnetic domain wall is magnetically movable along the easy axis of the free layer, and the free layer is magnetically coupled to magnetic fields generated by first and second currents running through first and second conductive lines crossing each other, wherein the easy axis of the free layer is inclined under an inclination angle relative to both the first and second conductive lines.

    摘要： A magnetic tunnel junction (MTJ) device is configured to store at least two bits of data in a single cell utilizing the variable resistance characteristic of a MTJ. The MTJ includes a soft and two fixed magnetic layers with fixed field directions oriented in perpendicular directions. The soft magnetic layer is separated from the fixed layers by insulating layers preferably with different thicknesses, or with different material compositions. The resulting junction resistance can exhibit at least four distinct resistance values dependent on the magnetic orientation of the free magnetic layer. The cell is configured using a pattern with four lobes to store two bits, and eight lobes to store three bits. The resulting cell can be used to provide a fast, non-volatile magnetic random access memory (MRAM) with high density and no need to rewrite stored data after they are read, or as a fast galvanic isolator.
