   Författare :Zhongwei Si; Mikael Skoglund; Ragnar Thobaben; Michael Lentmaier; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SRA - ICT; SRA - Informations- och kommunikationsteknik;

   Sammanfattning : LDPC convolutional codes, also known as spatially coupled LDPC codes, have attracted considerable attention due to their promising properties. By coupling the protographs from different positions into a chain and terminating the chain properly, the resulting convolutional-like LDPC code ensemble is able to produce capacity-achieving performance in the limit of large parameters.

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

   Författare :Si Chen; Chalmers tekniska högskola; []
   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

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

   Författare :Si Chen; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 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

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

   Författare :Si Chen; Shili Zhang; Jan Linnros; Christian Schönenberger; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 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

7. 5. Miniaturized localized surface plasmon resonance biosensors

   Författare :Si Chen; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; 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.
