  1. 21. Electrochemical Capacitors for Miniaturized Self-powered Systems

    Författare :Qi Li; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Electrolyte materials; Electrochemical capacitors; AC line filters; Energy storage; Miniaturized self-powered systems; Electrode materials;

    Sammanfattning : Miniaturized self-powered systems with harvest-store-use architectures have been recognized as a key enabler to the internet-of-things (IoT), and further the internet-of-everything (IoE), 5G communication and tactile internet. Electrochemical capacitors (ECs), also known as supercapacitors, are promoted to be the energy storage component in such systems, because of their advantages such as an almost limitless cycle life that is ideal for the vision of “fit-and-forget” maintenance-free networks.

  3. 22. Characterizations of as grown and functionalized epitaxial graphene grown on SiC surfaces

    Författare :Chao Xia; Chariya Virojanadara; Lars Hultman; Thomas Seyller; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The superior electronic and mechanical properties of Graphene have promoted graphene to become one of the most promising candidates for next generation of electronic devices. Epitaxial growth of graphene by sublimation of Si from Silicon Carbide (SiC) substrates avoids the hazardous transfer process for large scale fabrication of graphene based electronic devices.

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; silicon; nanocrystals; quantum dots; photoluminescence; optics; emission; absorption; Fysik; Physics;

    Sammanfattning : For over 60 years silicon (Si) has dominated the semiconductor microelectronics industry mainly due to its abundance and good electrical and material properties. The advanced processing technology of Si has made it the workhorse for photovoltaics industry as well. LÄS MER

  5. 24. Microfabrication and Integration Using Sub-Picosecond Laser Pulses and Magnetic Assembly

    Författare :Miku Laakso; Frank Niklaus; Massimo Mastrangeli; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Microfabricated devices and systems have many exciting applications such as accelerometers for triggering the launching of airbags in cars, gyroscopes for sensing the rotations of mobile phones, and micromirror arrays for controlling light reflection in digital light projectors. These devices are currently produced using semiconductor manufacturing techniques, which are suitable for large volumes of mostly planar structures. LÄS MER
