Carbon nanotubes are of great interest in fundamental research, with many one-dimensional physics concepts confirmed experimentally, such as electron and phonon confinement and singularities in the density of states. Some phenomena, like Luttinger-liquid behavior, remain debated. Their chemical stability, mechanical strength, and electrical conductivity suggest numerous applications, including nano-transistors, field-emission displays, artificial muscles, and alloy reinforcements. This text serves as an introduction to the physical concepts necessary for studying carbon nanotubes and other one-dimensional solid-state systems, targeting a broad scientific audience. Each chapter provides an accessible approach to the topics and sustainable solutions, making it comprehensible for physicists and chemists alike. It uniquely combines theoretical and experimental insights on subjects like carbon nanotube luminescence, Raman scattering, and transport measurements. The theoretical discussions range from the tight-binding approximation to first-principles simulations, emphasizing a thorough understanding of carbon nanotubes. Key topics include one-dimensional system concepts, nanotube symmetry, textbook models, ab-initio calculations, luminescence excitation spectroscopy linked to Raman spectroscopy, 1D transport properties, effects of bundling on electronic and vibrational characteristics, and resonance Raman scattering in nanotubes.
