Nano granular materials (NGM) are provided that have the extraordinary capability to conduct current in a 100 fold current density compared to high Tc superconductors by charges moving in form of Bosons produced by Bose-Einstein-Condensation (BEC) in overlapping excitonic surface orbital states at room temperature and has a light dependent conductivity. The material is disposed between electrically conductive connections and is a nano-crystalline composite material. Also provided are electrical components comprising NGM and methods and arrangements for making it by corpuscular-beam induced deposition applied to a substrate, using inorganic compounds being adsorbed on the surface of the substrate owing to their vapor pressure, and which render a crystalline conducting phase embedded in an inorganic insolating matrix enclosing the material.

Optical spectroscopy device and method for its manufacture

The invention relates to a device for generating electromagnetic THz radiation with free electron beams, comprising a dynatron tube, where the dynatron tube comprises an electron source, an extraction grid, and, an anode preferably coated with a material composition for high secondary electron emission, arranged in vacuum. The dynatron tube is connected to a voltage supply supplying an extractor voltage and an anode voltage and the extractor voltage is higher than the anode voltage. An oscillator modulates the anode voltage and the anode voltage is set to a work point voltage.

A material processing system for processing a work piece is provided. The material processing is effected by supplying a reactive gas and energetic radiation for activation of the reactive gas to a surrounding of a location of the work piece to be processed. The radiation is preferably provided by an electron microscope. An objective lens of the electron microscope is preferably disposed between a detector of the electron microscope and the work piece. A gas supply arrangement of the material processing system comprises a valve disposed spaced apart from the processing location, a gas volume between the valve and a location of emergence of the reaction gas being small. The gas supply arrangement further comprises a temperature-adjusted, especially cooled reservoir for accommodating a starting material for the reactive gas.

Material processing system and method

The matter for which the refractive index is to be determined, is made available in the form of a theoretically determinable scattering or diffraction pattern. Two or more orders of diffraction may then be defined to form at least one intensity ratio. At least one intensity distribution may be formed by irradiating the scattering pattern using one light beam of a defined shape. Subsequently thereto, the intensity ratio may be formed based on the orders of diffraction of the intensity distribution. In addition, at least one portion of a characteristic curve may be determined, which represents the dependency of the intensity ratio on the refractive index, and, with whose assistance, the corresponding refractive index can be assigned to the intensity ratio formed.

Method for determining a refractive index

A miniaturized terahertz radiation source based on the Smith-Purcell effect is provided, in which, from a focused electron source, a high-energy bundle of electrons is transmitted at a defined distance over a reflection diffraction grating composed of transversely disposed grating rods, so that, in response to oscillating image charges, electromagnetic waves of one wavelength are emitted, the wavelength being adjustable as a function of the periodicity of the lines and of the electron velocity. The elements of the radiation source, such as field emitter (), electrostatic lens (), beam deflector (), grating () of metal, and a second anode (), are integrated on a semiconductor chip using additive nanolithographic methods. The field electron source is constructed to project, as a wire, out of the surface, using additive nanolithography, and is made of readily conductive material having stabilizing series resistance. The wire is constructed, using computer-controlled deposition lithography, in a straight or curved, free-standing design. In its surface area, the base material bears a conductor structure for the electrical terminals and connections (), including controllable voltage sources () for supplying the field emitter tips (), lens (), and control electrodes (). The terahertz radiation source is designed to be a powerful component that is available in modular form and is usable in any spatial situation.

Inordinate localised systems are used at room temperature in a novel device in the form of an electron spectrometer for utilising single-electron electronic applications. Said electron spectrometer device consists of a nanocrystalline metal or a nanocrystalline semiconductor material used as conductor strip connection in the form of an inlet or an outlet for single-electron electronic components and circuits consisting of lithographically produced quantum dots. The resulting single-electron electronic device consisting of quantum dots is supplied with energetically very sharply defined electrons. Said device can thus be operated at room temperature, undisturbed by phonons.
