Suspended single-electron transistors: Fabrication and measurement

2005

We have fabricated aluminum single-electron transistors in which the island is not in contact with the substrate. This new type of device, which can be called suspended single-electron transistor (SUSET), displayed well-defined I-V and dI/dV-V features typical for high-quality standard SET's.

Superconductivity suppression in Fe-implanted thin Al films

2005

At present, ion implantation into metallic systems is given increasing attention, aiming at achieving properties and functionalities of technologically valuable materials not easily available via conventional techniques. In our experiments thin Al films were implanted with Fe ions in order to find out how the superconductive properties of the metal can be modified at will. The purpose was twofold, viz., first, to study the basic physics of superconductivity in low-dimensional metallic structures doped with impurities. The second purpose was to apply ion implantation for the suppression of undesired superconductivity in aluminum widely used for fabrication of micro- and nanodevices operated …

Fabrication of Quasi-One-Dimensional Superconducting Micro- and Nanostructures

2007

Wires capable of conducting electric current are basic blocks of all electronic applications. Of particular interest for nanoelectronics are superconducting elements taking advantage of the superconductor's macroscopic quantum coherence and zero resistance. Recently there appeared indications that due to quantum fluctuations the dissipationless electric current (supercurrent) can be suppressed in ultra-narrow superconducting channels with the effective diameter below approximately 10 nm. In this Review we will describe methods of fabrication of quasi-one-dimensional superconducting micro- and nanowires suitable for electric transport measurements at cryogenic temperatures. In the first sect…

Ag/(Bi, Pb)-Sr-Ca-Cu-O superconducting tape processing: Solid state chemistry aspects

1993

Abstract Different preparation methods have been used to obtain starting powders used in the fabrication of composite tapes by the powder-in-tube method. The effect of these distinct starting powders on the superconducting properties of Ag/Bi-Sr-Ca-Cu-O monofilament tapes has been investigated. The changes in the physical properties, including the critical current density at 77 K and ac magnetic susceptibility, and microstructure, using optical and electronic microscopy, have been analyzed in relation to the solid state reactions involved in the Bi 2 Sr 2 CaCu 2 O 8+δ and Bi 2 Sr 2 Ca 2 Cu 3 O 10+δ phase transformations.

Integration of GMR sensors with different technologies

2016

Less than thirty years after the giant magnetoresistance (GMR) effect was described, GMR sensors are the preferred choice in many applications demanding the measurement of low magnetic fields in small volumes. This rapid deployment from theoretical basis to market and state-of-the-art applications can be explained by the combination of excellent inherent properties with the feasibility of fabrication, allowing the real integration with many other standard technologies. In this paper, we present a review focusing on how this capability of integration has allowed the improvement of the inherent capabilities and, therefore, the range of application of GMR sensors. After briefly describing the …

Ejes de creación del valor relacional entre fabricantes y minoristas de productos duraderos

2016

El principal papel del marketing está basado en la creación de valor por las partes implicadas en el intercambio (AMA, 2013). Desde este punto de vista, existe un contexto de estudio que ha experimentado un interés creciente en la literatura y que tiene que ver con la creación de valor entre empresas. A esta rama del estudio del valor se la conoce como valor relacional. El valor relacional se define como el balance de sacrificios y costes percibidos por parte de un cliente en una relación con un proveedor (Eggert y Ulaga, 2010). Se trata de un constructo dinámico que se ha fundamentado tradicionalmente a partir de la teoría de intercambio. Sin embargo, la evolución del marketing hacia una n…

I sapori dei tatuaggi nell'Amazzonia indigena

2018

Through an analysis of some ethnographic examples (Matis, Akawaio,Guayaki, Cayabi), the chapter shows how in Indigenous Amazonia tattooing was connected in multiple ways to cultural conceptions regarding both the fabrication of the person and the classifications of world components, in which complex systems of correspondence between diverse domains organize people's experience and thought.

Technology Comprehension — Combining computing, design, and societal reflection as a national subject

2019

This article considers the implementation of a new learning subject ”Technology Comprehension” into lower secondary schools in Denmark, as part of an initiative by the Danish Ministry of Education. The subject consists of learning objectives related to computing, design, and societal reflection and was first introduced as an elective course in 13 schools to investigate how it could be integrated into the Danish education system. We present four key findings based on school visits, interviews, an electronical survey, two questionnaires, and workshops including theme discussions: (1) teachers did not perceive Technology Comprehension as a distinct subject, but rather as a set of skills that c…

Demand Response Service Certification and Customer Baseline Evaluation Using Blockchain Technology

2020

The use of Distributed Ledger Technologies such as Blockchain for certifying Demand Response services allows for the creation of a distributed system in which customers can communicate with the system operator to provide their flexibility, in a secure, transparent and traceable way. Blockchain technology also supports incentive mechanisms for users taking part in the service through the generation of utility tokens to recognize the user's contribution. This paper presents the experimental test of a novel methodology for Demand Response programs implementation by using the Blockchain technology. The latter is employed for defining a distributed Demand Response service and a new system for it…
