High-quality ultralong Sb2Se3 and Sb2S3 nanoribbons on a large scale via a simple chemical route

Article Abstract:

Large-scale ultralong single-crystalline Sb2Se3 and Sb2S3 nanoribbons are made respectively by reacting SbCl3 with selenium and sulfur powders in glycol solution. The growth mechanism of the nanoribbons is examined based on high-resolution transmission electron microscopy and the optical absorption experiment has revealed that Sb2Se3 and Sb2S3 nanoribbons are two semicompounds with bandwidth [E.sub.g] approximately and equal to 1.15 eV and [E.sub.g] approximately and equal to 1.56 eV, respectively.

High-quality ultralong Bi2S3 nanowires: Structure, growth, and properties

Article Abstract:

A simple one-step hydrothermal method for large-scale synthesis of ultralong single-crystalline Bi2S3 nanowires was reported and the nanowires were comprehensively characterized. The structure of the nanowires was determined to be of the orthorhombic phase, the growth direction was along [001] and the growth mechanism was investigated based on extensive high-resolution transmission electron microscopy observations.

Effect of H2 on the electrical transport properties of single Bi2S3 nanowires

Article Abstract:

A study fabricated field effect transistors using Bi2S3 nanowires. It was found that the current of Bi2S3 nanowires is found to increase remarkably in H2 compared to that in a vacuum and that H2 enhances electronic mobility and carrier density within the nanowires dramatically.
