Superconducting electronics

During the last decades superconducting electronics has been the most prominent area of research for small scale applications of superconductivity. It has experienced quite a stormy development, from individual low frequency devices to devices with high integration density and pico second switching time. Nowadays it offers small losses, high speed and the potential for large scale integration and is superior to semiconducting devices in many ways ¿ apart from the need for cooling by liquid helium for devices based on classical superconductors like niobium, or cooling by liquid nitrogen or cryocoolers (40K to 77K) for high-Tc superconductors like YBa2Cu3O7. This article gives a short overview over the current state of the art on typical devices out of the main application areas of superconducting electronics

Electronics and control technology

Until recently, there was no requirement to learn electronics and control technology in the New Zealand school curriculum. Apart from isolated pockets of teaching based on the enthusiasm of individual teachers, there is very little direct learning of electronics in New Zealand primary or secondary schools. The learning of electronics is located in tertiary vocational training programmes. Thus, few school students learn about electronics and few school teachers have experience in teaching it. Lack of experience with electronics (other than using its products) has contributed to a commonly held view of electronics as out of the control and intellectual grasp of the average person; the domain of the engineer, programmer and enthusiast with his or her special aptitude. This need not be true, but teachers' and parents' lack of experience with electronics is in danger of denying young learners access to the mainstream of modern technology

Chiral Electronics

We consider the properties of electric circuits involving Weyl semimetals. The existence of the anomaly-induced chiral magnetic current in a Weyl semimetal subjected to magnetic field causes an interesting and unusual behavior of such circuits. We consider two explicit examples: i) a circuit involving the "chiral battery" and ii) a circuit that can be used as a "quantum amplifier" of magnetic field. The unique properties of these circuits stem from the chiral anomaly and may be utilized for creating "chiral electronic" devices.Comment: 5 pages, 2 figures; final version to appear in Physical Review

Flexible workforces and low profit margins: electronics assembly between Europe and China

This book investigates restructuring in the electronics industry and in particular the impact of a \u2018Chinese\u2019 labour regime on work and employ - ment practices in electronics assembly in Europe.1 Electronics is an extremely dynamic sector, characterized by an ever-changing organi - zational structure, as well as cut-throat competition, particularly in manufacturing. Located primarily in East Asia, electronics assembly has become notorious for poor working conditions, low unionisation and authoritarian labour relations. However, hostile labour relations and topdown HR policies are not unique to East Asia. They have become associated with the way the sector is governed more broadly, with a number of Western companies also coming to rely on such practices

Foreign Direct Investment and Electronics Exports: Exploratory Empirical Evidence from Malaysia's Top Five Electronics Exports

The foreign direct investment (FDI) has contributed significantly to Malaysia's electronics exports as well as the growth and development of the electronics industry as a result of the export-oriented industrialization initiatives undertaken since 1970s. The aim of this study is to explore the causation between FDI and electronics exports by using Malaysia''s top five electronics exports by SITC (Standard International Trade Classification) product groups. The findings show a bi-directional causality between FDI and exports of semiconductor devices in the short run. The present study provides important policy implications towards the competitiveness of electronics exports and also promoting and targeting FDI inflows into key and priority growth in the electronics sub-sectors.

Optical electronics

The development of an optical diode consisting of a metal-dielectric-metal junction in which the high-speed electric conduction process occurs due to quantum mechanical electron tunneling across the dielectric barrier is briefly reviewed. Potential applications of the diode are discussed
