2. 1. A spectroscopic study of polymer : Carbon nanotube composites

   Author : Andreas Müller; Ove Andersson; Luleå tekniska universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik;

   Abstract : Since the identification of carbon nanotubes (CNTs) by Ijima in 1991, this material has become a subject of great interest and effort in science because of the outstanding physical properties it exhibits. CNTs can be thought of as graphene sheets rolled into seamless cylinders of various diameters and in principle infinite length. READ MORE

4. 2. Carbon nanotube/MF composites

   Author : Liliana Licea Jimenez; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nanocomposites; carbon nanotubes; melamine-formaldehyde;

   Abstract : A new generation of composites, frequently referred to as nanocomposites, are making research and engineering impact worldwide. Particularly, the incorporation of carbon nanotubes (CNT) into polymers is attractive, due to the generally good processability of polymers and the unprecedented properties of nanotubes. READ MORE

5. 3. Carbon Nanotubes for Electronic Packaging: Growth, Novel Devices and 3D Networks

   Author : Yifeng Fu; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; multi-scale modeling; electrospinning; microfin; PDMS; chemical vapor deposition CVD ; Carbon nanotube CNT ; double-walled CNT DWNT ; CNT covalent bonding; CNT transfer; thermal management; packaging;

   Abstract : Carbon nanotubes (CNTs) have shown great potential of application in electronics because of their attractive physical properties, such as high surface-to-volume ratio, high electron mobility, high Young’s modulus, high thermal conductivity, low thermal expansion coefficient, etc. However, many obstacles are yet to be removed to use CNTs as building blocks in electronic systems.

6. 4. Carbon Nanotube Transistors: Nanotube Growth, Contact Properties and Novel Devices

   Author : Johannes Svensson; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Carbon nanotube; chemical vapour deposition; Field effect transistor; Marangoni convection; Schottky barrier;

   Abstract : Carbon nanotubes (CNTs) are envisioned to be used as the basic building blocks in future electronics due to their excellent electronic properties such as high mobility, compatibility with high-k dielectrics and small diameters resulting in advantageous electrostatics. This thesis is divided into three separate topics related to increasing the fabrication yield and performance of CNT field effect transistors (CNTFETs). READ MORE

7. 5. Toward Carbon based NEMS

   Author : Farzan Alavian Ghavanini; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; carbon nanotubes CNT ; Nanoelectromechanical systems; and CMOS compatibility ; CNT-based switch; vertically aligned carbon nanofibers VACNF ; NEMS;

   Abstract : A systematic analysis and assessment of carbon nanotube (CNT) based NEMS switches is presented and their features are compared to typical complementary metal-oxide-semiconductor (CMOS) performance parameters. It is shown that CNT-based switches with considerably smaller leakage current compared to CMOS switches can be realized. READ MORE
