  1. 16. Silicon nanogaps: An electronic bridge to the molecular world

    Författare :Jonas Berg; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nanocrystals; TSRAM; Silicon nanogaps; Molecular electronics; Selective etching; Resonant Tunneling Diodes; Molecules;

    Sammanfattning : We have designed and manufactured silicon nanogaps aimed at electrically interfacing molecules, utilizing the precision thickness control in an oxidation process. An insulating layer was formed on a silicon wafer, and then polysilicon was deposited on top. LÄS MER

  3. 17. Crack-junctions : Bridging the gap between nano electronics and giga manufacturing

    Författare :Valentin Dubois; Göran Stemme; Christofer Hierold; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nanotechnology; nanoelectronics; nanogap electrodes; molecular electronics; nanoplasmonics; crack-junctions; break junctions; nanowires; parallel fabrication; lithography; fracture; crack; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Obtaining both nanometer precision of patterning and parallel fabrication on wafer-scale is currently not possible in conventional fabrication schemes. Just as we are looking beyond semiconductor technologies for next-generation electronics and photonics, our efforts turn to new ways of producing electronic and photonic interfaces with the nanoscale.

  4. 18. Feature Extraction for Low-Frequency Signal Classification

    Författare :José Chilo; Thomas Lindblad; Christian Bohm; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; infrasound; seismic signals; feature extraction; wavelets; fingerprints; mining; multimodal data space; Atomic physics; Atomfysik; Electronics;

    Sammanfattning : The development of the International Monitoring System (IMS) for the verification of the Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO) has led to a rapid revival of interest in infrasound. Furthermore, the installation of low-frequency sensors at seismic sites has increased in recent years, providing researchers with large and heterogeneous data-sets in near real-time. LÄS MER

  5. 19. Molecular Electronic Devices based on Ru(II) Thiophenyl Pyridine and Thienopyridine Architecture

    Författare :Robert Steen; Simon Dunne; Sarah Angus-Dunne; Kenneth Wärnmark; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Molecular Electronics; Organic Synthesis; Ruthenium; Pyridyl Complexes; Ligand Design; Fused Ligands; Chemical engineering; Kemiteknik; Biotechnology Chemical Engineering; bioteknik kemiteknik;

    Sammanfattning : According to the famous axiom known as Moore’s Law the number of transistors that can be etched on a given piece of ultra-pure silicon, and therefore the computing power, will double every 18 to 24 months. However, around 2020 hardware manufacturers will have reached the physical limits of silicon. LÄS MER

  7. 20. Fabrication, functionalization and electrical conductance modulation of nanoparticle based molecular electronic Nano-devices

    Författare :Ishtiaq Hassan Wani; KLAUS LEIFER; Silvia Karthäuser; Uppsala universitet; []
    Nyckelord :Molecular electronics; gas sensor; hybrid materials; place exchange; random telegraph signal;

    Sammanfattning : Over the years many techniques have been proposed for the purpose of the formation of electrically conducting metal-molecule-metal junctions. One such technique utilizes gold-nanoparticles (AuNPs) that could assist in contacting small molecules between large gaps. LÄS MER
