1. Mechanical properties of carbon nanotubes and nanofibers
Sammanfattning : Carbon nanotubes (CNTs) have extraordinary electrical and mechanical properties, and many potential applications have been proposed, ranging from nanoscale devices to reinforcement of macroscopic structures. However, due to their small sizes, characterization of their mechanical properties and deformation behaviours are major challenges. LÄS MER
2. Synthesis and characterization of vertically aligned carbon nanofibers for nanoscale devices
Sammanfattning : The synthesis of vertically aligned carbon nanofibers (VACNFs) by direct current plasma enhanced chemical vapor deposition (dc PECVD) has presented a unique opportunity to realize nanoscale three-dimensional devices at a reasonable cost. The determinism offered by the synthesis process in terms of control over the spatial and the geometrical properties of the resulting nanofibers provides a powerful tool to implement a wide range of applications from nanoelectromechanical systems to biological devices.

3. Toward Carbon based NEMS
Sammanfattning : 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. LÄS MER
4. Carbon nanomaterial-based interconnects, integrated capacitors and supercapacitors
Sammanfattning : The constant miniaturization and steady performance improvement of electronics devices have generated innovative ideas such as internet of thing (IoT), which also includes devices with integrated energy sources. The high performance is conceived by the high density of the devices on a chip leading to a high density of interconnects, to connect these devices to outside world. LÄS MER
5. Application of Metallic Nanoparticles and Vertically Aligned Carbon Nanotubes as Interconnect Materials for Electronics Packaging
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
