  1. 1. Silicon Nanowire Field-Effect Devices as Low-Noise Sensors

    Författare :Xi Chen; Zhen Zhang; Shi-Li Zhang; Si Chen; Fengnian Xia; Uppsala universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Silicon nanowire; field-effect transistor; Schottky junction gate; low frequency noise; ion sensor; Teknisk fysik med inriktning mot elektronik; Engineering Science with specialization in Electronics;

    Sammanfattning : In the past decades, silicon nanowire field-effect transistors (SiNWFETs) have been explored for label-free, highly sensitive, and real-time detections of chemical and biological species. The SiNWFETs are anticipated for sensing analyte at ultralow concentrations, even at single-molecule level, owing to their significantly improved charge sensitivity over large-area FETs. LÄS MER

  2. 2. Application of Metallic Nanoparticles and Vertically Aligned Carbon Nanotubes as Interconnect Materials for Electronics Packaging

    Författare :Si Chen; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Carbon nanofibers; Fracture surface; Electronics packaging; Thermal fatigue; Electrical resistance; Shear strength; Interconnect materials; Nanocomposite solder;

    Sammanfattning : In the electronics industry, packaging is responsible to protect chip from atmosphere and provide the path for signal communication as well as thermal dissipation. The realization of these functions in a packaging system depends on the performance of interconnect materials. Any failure on the interconnect materials could make entire system down. LÄS MER

  3. 3. Characterization of Nanomaterials for Interconnect and Thermal Management in Electronic Packaging

    Författare :Si Chen; Chalmers University of Technology; []
    Nyckelord :heat dissipation; electronic packaging; nanomaterial; characterization; thermal interface material; solder; thermoelectric.; interconnect; through silicon via;

    Sammanfattning : Electronic packaging, protecting the fragile chip from atmosphere and providing the paths for signal transmission as well as heat dissipation, is one of the most important parts in electronic devices. The cost, dimensions, performance, and reliability of an electronic device therefore strongly depend on its packaging structures and materials. LÄS MER

  4. 4. Electronic Sensors Based on Nanostructured Field-Effect Devices

    Författare :Si Chen; Shili Zhang; Jan Linnros; Christian Schönenberger; Uppsala universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biosensor; field-effect transistor; nanowire; ISFET; Elektronik; Electronics;

    Sammanfattning : Point-of-care (POC) diagnostics presents a giant market opportunity with profound societal impact. In particular, specific detection of DNA and protein markers can be essential for early diagnosis of e.g. cancer, cardiovascular disease, infections or allergies. LÄS MER

  5. 5. Miniaturized localized surface plasmon resonance biosensors

    Författare :Si Chen; Chalmers University of Technology; []
    Nyckelord :colloidal lithography; Surface plasmon resonance; biosensing; electron beam lithography; single molecule; hyperspectral imaging; photo functionalization;

    Sammanfattning : Abstract Reliable and sensitive biosensors are required for fast and accurate diagnostics. Localized surface plasmon resonances (LSPRs) in noble-metal nanoparticles possess very high refractive index sensitivity close to the metal surface and therefore constitute an attractive biosensing platform.
