abstract

  • Control over the dimensions and shape of nanostructures represents one of the main challenges in modern materials science. Morphology control of a variety of materials can be achieved using vapor–liquid–solid [1, 2] or solution–liquid–solid techniques [3] to obtain one- dimensional (1D) systems. The unique optical and electrical properties of 1D nanostructures make them one of most important building blocks for nanoscience and nanotechnology applications, and provide the opportunity for their integration in electronic, photonic,[4] thermoelectric, and sensor-based devices.[5] Size control has been traditionally important and necessary to tune the optical and electrical properties of nanomaterials by changing the band gap. This is particularly important in the strong confinement region, where one of the dimensions is smaller than the corresponding excitonic Bohr diameter.[6] Semiconductor …
