20.500.12556/DiRROS-22509 Modulations of the work function and morphology of a single ▫$MoS_2$▫ nanotube by charge injection Both the miniaturization of transistor components and the ongoing investigation of material systems with potential for quantum information processing have significantly increased current interest of researchers in semiconducting inorganic nanotubes. Here we report on an additional outstanding aspect of these nanostructures, namely the intrinsic coupling of electronic and mechanical properties. We observe electronic and morphology changes in a single MoS2 nanotube, exposed to charge injections by means of an atomic-force-microscopy tip. An elliptic deformation of the nanotube and helical twisting of the nanotube are visible, consistent with the reverse piezoelectric effect. Work-function changes are found to be dependent on the polarity of the injected carriers. An unexpected long-term persistence of the shape deformations is observed and explained with accumulation of structural defects and the resultant strain, which could cause a memory-like charge confinement and a long lasting modulation of the work function. dichalcogenide crystals semiconducting inorganic nanotubes charge injection nanotubes true false true The Royal Society of Chemistry Združeno kraljestvo Angleški jezik Ni določen © 2024 The Author(s).
