Patterning of Carbon Nanotubes on Silicon Wafer Using Self-Assembly Techniques

R. Balachander, G. Sakthivel


Nanotechnology is an emerging technology that enables scientists to develop new materials and products at the molecular level. A carbon nanotube (CNT) is a rolled sheet of carbon atoms, coaxially arranged in cylindrical shape. Single-walled CNTs are ideal quantum systems for exploring basic science in one dimension. To find use in electronics, single-walled CNTs need to be efficiently separated by electronic type and aligned to ensure optimal and reproducible electronic properties. Using self-assembly techniques, an attempt was made at selectively patterning and sorting semiconducting versus metallic SWCNTs on (3-aminopropyl)triethoxysilane (APTES) and phenyl triethoxysilane (PTEOS) coated films on Si (100). The patterned substrates were characterized using atomic force microscopy (AFM), optical microscopy, scanning electron microscopy (SEM) and Raman spectroscopy.
