Abstract

Un proceso para la fabricacion de junturas Josephson en escala nanométrica utilizando un microscopio de fuerza atomica (AFM) en el modo indentacion y técnicas usuales de litografía optica. El sistema consta de un electrodo inferior superconductor, una barrera metálica o aislante y un electrodo superior superconductor metálico. La utilizacion de la nanoindentacion permite reducir el tamano característico de la juntura lo que aumenta la homogeneidad de la barrera, y permite solucionar el problema de los defectos de superficies en superconductores de alta temperatura crítica. El método incluye la fabricacion dispositivos electronicos basados en nanojunturas Josephson para su aplicacion en el desarrollo de nano-SQUIDS como sensores magnéticos para nano-objetos.A process for the manufacture of Josephson joints on a nanometric scale using an atomic force microscope (AFM) in the indentation mode and usual optical lithography techniques. The system consists of a superconducting lower electrode, a metallic or insulating barrier and a metallic superconducting upper electrode. The use of nanoindentacion allows to reduce the characteristic size of the joint which increases the homogeneity of the barrier, and allows solving the problem of surface defects in critical high temperature superconductors. The method includes the manufacture of electronic devices based on Josephson nano junctions for application in the development of nano-SQUIDS as magnetic sensors for nano-objects.
