INDEPENDENT SELF-COOLED NANOINSTRUMENT AND ITS FORMATION METHOD

FIELD: heating.SUBSTANCE: invention relates to formation methods of independent self-cooled instruments and elements of electronics, which can operate effectively without using any liquid nitrogen technology and other cryogenic equipment. The formation method of an independent self-cooled nanoinstrument consists in the fact that on a substrate from monocrystalline material with a squid receiver formed on one side there arranged on the reverse side is a heat absorption device that includes a cathode and an anode, which have different Fermi energy of electrons. Then, the substrate is enclosed through an installation hole in a vacuum cover from ceramised glass which contains contact electrodes for two substrate sides. After that, the substrate installation hole is closed with a cover from ceramised glass. This device is arranged in a vacuum chamber in which a target from ceramised glass is arranged as well. Pumping-out to the pressure of 10Pa is performed; the target and the cover from ceramised glass is heated up to 450÷500°C. Then, by means of a laser with wavelength of radiation equal to 1.06 mcm, pulse duration of 10-20 ns and pulse repetition frequency of 10 Hz, power density of 5·10÷8·10W/cmthere the target from ceramised glass is sprayed, which is located at the distance of 8÷10 mm from the cover from ceramised glass during 10 minutes.EFFECT: invention provides creation of such design of a squid (a superconducting quantum interference device), in which the following is excluded: degradation of superconducting properties in the air medium, dependence of achievement of operating temperature on use of liquid nitrogen or other external cryogenic units with large dimensions.1 dwg Изобретение относиться к способам формирования самоохлаждаемых автономных приборов и элементов электроники, которые могут эффективно работать без использования технологии жидкого азота, и другой криогенной техники. Способ формирования самоохлаждаемого автономного наноприбора заключается в том, что на подложке из монокристаллического материала с сформированным с одной стороны СКВИД-приемником на обратной стороне размещают устройство для поглощения тепла, которое содержит катод и анод, имеющие различную энергию Ферми электронов. Затем подложку через отверстие для монтажа заключают в вакуумную оболочку из ситалла, содержащую контактные электроды для двух сторон подложки. После этого отверстие для монтажа подложки закрывают крышкой из ситалла. Размещают данное устройство в вакуумной ка
