摘要:
Quantum-size electronic devices comprise electrodes and at least one cluster separated from the said electrodes by a tunnel-transparent gap. The characteristic dimensions for elements of quantum-size devices are determined by the formula in the range 1÷4 r 0 , wherein r 0 = ℏ/(m e α 2 c), wherein ℏ is Planck's constant, m e is the electron mass, α= 1/137,036 is the fine structure constant, c is the light speed. The cluster may be made of a semiconductor material, conductor, superconductor, high-molecular substance or a covering with a tunnel-transparent dielectric. The matured theory provides possibilities for designing logical devices operating in the mode of transfer and/or storing of several electrons at normal conditions and high temperatures. The operating conditions of the devices are determined. The invention provides basic condition for constructing of high-temperature superconducting components and devices based thereon, as well as for transmitting electric signals and energy loss-free.

The first tunneling structure includes at least a first amorphous insulating layer and a different, second insulating layer such that the transport of electrons includes transport by means of tunneling. The transistor further includes a second tunneling structure disposed between the base and collector electrodes. The second tunneling structure serves as a transport of at least a portion of the previously mentioned electrons between the base and collector electrodes by means of ballistic transport such that the portion of the electrons is collected at the collector electrode.
摘要:
Changes in the infrared reflection spectrum of a thin film of silica-like resinous material sandwiched between metal electrodes can be induced by applying an electric potential to a top electrode which is semitransparent. Characteristic infrared absorption lines change in proportion to a small electric current flowing through the material. These changes occur with response times of the order of seconds, and show time constants of the order of minutes to reach stationary values.

A method for stabilizing a tunnel junction component, in which a mask is formed on the surface of a substrate, and conductors (3, 4) are constructed by evaporation onto the substrate in an evaporation chamber, and at least one thin oxide layer element (5) is oxidized on top of a selected conductor (3). This remains partly under the following conductor (4), thus forming a tunnel junction element (2) with those conductors (3, 4), and titanium (Ti) or another gettering substance is evaporated on top of the said following conductor (4), before the tunnel junction component is removed from the evaporation chamber, when the titanium layer (7) thus created protects the tunnel junction element (2) from the detrimental effects of air molecules.
