1. 1. Graphene Hot-electron Transistors

   Författare :Sam Vaziri; Mikael Östling; Max Lemme; Suman Datta; KTH; []
   Nyckelord :Graphene; hot-electron transistors; graphene base transistors; GBT; cross-plane carrier transport; tunneling; ballistic transport; heterojunction transistors; graphene integration; graphene transfer; Informations- och kommunikationsteknik; Information and Communication Technology;

   Sammanfattning : Graphene base transistors (GBTs) have been, recently, proposed to overcome the intrinsic limitations of the graphene field effect transistors (GFETs) and exploit the graphene unique properties in high frequency (HF) applications. These devices utilize single layer graphene as the base material in the vertical hot-electron transistors. LÄS MER

3. 2. Graphene Heat Spreaders for Electronics Thermal Management Applications

   Författare :Yong Zhang; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; test platform; heat spreader.; transfer; Graphene; thermal management;

   Sammanfattning : Graphene shows great potential for applications in electronics due to its outstanding physical properties such as extremely high electron mobility, high thermal conductivity, high Young’s modulus and very high surface-to-volume ratio. Among these attractive properties, the high intrinsic thermal conductivity is a critical advantage for the application of graphene in electronics to alleviate heat dissipation problems. LÄS MER

4. 3. Towards 3D Integration of Carbon Based Electronics

   Författare :Wei Mu; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; transfer; carbon nanomaterials; polymer filling; MWCNTs; interconnect; 3D integration; packaging; graphene; horizontally aligned SWCNTs; through silicon via;

   Sammanfattning : Carbon-based nanomaterials such as carbon nanotubes (CNTs) and graphene, which possess superior electrical, thermal and mechanical properties, have been proposed as alternative materials for future electronics. The proposed applications span from the device level, replacing silicon-based transistors, with single-walled carbon nanotubes (SWCNTs) or graphene, to packaging level using multi-walled carbon nanotubes (MWCNTs) for interconnects.

   Sammanfattning : Biosensors are devices that detect biological elements and then transmit a readable signal. Biosensors can automatize diagnostics that would otherwise have to be performed by a physician or perhaps not be possible to perform at all. Current biosensors are however either limited to particular diseases or prohibitively expensive. LÄS MER
