The series Topics in Current Chemistry Collections presents critical reviews from the journal Topics in Current Chemistry organized in topical volumes. The scope of coverage is all areas of chemical science including the interfaces with related disciplines such as biology, medicine and materials science. The goal of each thematic volume is to give the non-specialist reader, whether in academia or industry, a comprehensive insight into an area where new research is emerging which is of interest to a larger scientific audience. Each review within the volume critically surveys one aspect of that topic and places it within the context of the volume as a whole. The most significant developments of the last 5 to 10 years are presented using selected examples to illustrate the principles discussed. The coverage is not intended to be an exhaustive summary of the field or include large quantities of data, but should rather be conceptual, concentrating on the methodological thinking that will allow the non-specialist reader to understand the information presented. Contributions also offer an outlook on potential future developments in the field.

Carbon nanotubes are promising candidates for enhancing electronic devices in the future at the nanoscale level. Their integration into todays electronics has however been challenging due to the difficulties in controlling their orientation, location, chirality and diameter during formation. This thesis investigates and develops new techniques for the controlled growth and assembly of carbon nanotubes as a way to address some of these challenges. Colloidal lithography using nanospheres of 450 nm in diameter, acting as a shadow mask during metal evaporation, has been used to pattern thin films of single-walled carbon nanotube multilayer catalysts on Si and Si/SiO2 substrates. Large areas of periodic hexagonal catalyst islands were formed and chemical vapor deposition resulted in aligned single-walled carbon nanotubes on Si substrates within the hexagonal array of catalyst islands. On silicon dioxide, single-walled carbon nanotubes connecting the hexagonal catalyst islands were observed. To help explain these observations, a growth model based on experimental data has been used. Electrostatic interaction, van der Waals interaction and gas flow appear to be the main forces contributing to single-walled carbon nanotube alignment on Si/SiO2. Although the alignment of single-walled carbon nanotubes on Si substrates is still not fully understood, it may be due to a combination of the above factors, in addition to silicide-nanotube interaction. Atomic force microscopy and Raman spectroscopy of the post-growth samples show single-walled carbon nanotubes of 1-2 nm in diameter. Based on the atomic force microscopy data and Raman spectra, a mixture of individual and bundles of metallic and semiconducting nanotubes were inferred to be present. A novel technique based on direct nanowriting of carbon nanotube catalysts in liquid form has also been developed. The reliability of this method to produce nanoscale catalyst geometries in a highly controlled manner, as required for carbo.

Single-walled carbon nanotubes (SWCNTs) are cylindrical one-dimensional nanomaterials made of single-layered graphene sheets. They possess unique properties because of their specific structure. Due to their distinct electronic structure and impressive thermal, mechanical, and optical properties, SWCNTs have great applications in biomedicine, energy storage, nanomechanical devices, etc. So far, many methods have been developed to synthesize SWCNTs. Despite the great achievements in the synthesis and applications of SWCNTs in the past few decades, many challenges remain. This primer will equip the reader with a foundational understanding of the growth mechanisms of SWCNTs and the advantages and disadvantages of the process and growth conditions of the various techniques. The reader will also learn how to relate the properties and structure of these materials to their specific functionality in the desired application.

Single Walled Carbon Nanotubes (SWNTs) are being considered building blocks for next generation electronics due to their unique electrical, mechanical and thermal properties. A number of SWNT based devices including scanning probes, field emitters, field effect transistors, biological and chemical sensors, and memory devices have been demonstrated. Despite successful demonstration of these single devices, the success of SWNT based nanoelectronics is hampered due to the lack of a successful nano-manufacturing method. Precise alignment and placement of SWNTs is necessary for successful integration of SWNTs into nanoelectronics. The work described in this thesis is focused on developing electric field assisted assembly techniques for precise placement and controlled orientation of SWNTs. In a first set of experiments we evaluate the use of micro/nano finger shaped metal electrodes to assemble SWNTs. Even though this assembly technique help in understanding the electrophoretic behavior of SWNTs, problems related with orientation, assembly at nanoscale and electrode degradation demanded evaluating alternative techniques. Nanotemplates that use trenches made in PMMA on a conductive substrate are utilized for the directed, controlled assembly of SWNTs This technique uses a combination of electrophoretic forces and fluidic forces to assemble and align the SWNTs. We were able to assemble SWNTs in trenches that are as small as 80 nm wide and 100,000 nm long over a 2.25 cm2 area in 30-90 seconds. Based on the experimental results and analysis a model is proposed to explain the assembly and alignment mechanism of SWNT s. The technique has been utilized to fabricated interconnects and field effect transistors to demonstrate the feasibility to make devices. Finally we introduce a novel room temperature assembly technique for fabricating a three dimensional single walled carbon nanotube platform. A top down lithographic approach is used to fabricate the platform while a bottom-up dielectrophoresis method is used to assemble the SWNTs in a 3D architecture. This is a scalable, high throughput and room temperature technique making it compatible with current CMOS technology. We demonstrate the ability to precisely control the density of SWNTs. A finite element model is used to simulate and study the behavior the SWNTs during assembly. We also demonstrate that these structures can be utilized directly as 3D interconnects. Finally, we show that the packaging of these devices, using a conformal pin-free parylene layer, provides a complete process flow for making SWNT based 3D nano-devices.

Single-walled carbon nanotubes (SWCNTs) have recently attracted tremendous interest as a nanomaterial for photonics and quantum photonics devices. Here we shall review recent work with a focus on quantum light properties such as blinking and spectral diffusion, and in particular, methods and techniques to suppress these detrimental effects with the goal of enhancing optical emission. Furthermore, we shall review recent work on the generation and detection of nonclassical light emissions from individual SWCNTs embedded in polymer cavities, and discuss the role of spatial exciton localization along the tube.
