  1. 11. Carbon nanomaterial-based interconnects, integrated capacitors and supercapacitors

    Författare :Muhammad Amin; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; carbon nanotubes; Integrated capacitors; vertically aligned carbon nanofibers; Interconnects; PECVD; Interdigitated micro-supercapacitors;

    Sammanfattning : The constant miniaturization and steady performance improvement of electronics devices have generated innovative ideas such as internet of thing (IoT), which also includes devices with integrated energy sources. The high performance is conceived by the high density of the devices on a chip leading to a high density of interconnects, to connect these devices to outside world. LÄS MER
