Electrostimulation and Nanomanipulation of Two-Dimensional MoO3-x Layers Grown on Graphite

Molybdenum trioxide shows many attractive properties, such as a wide electronic band gap and high relative permittivity. Monolayers of this material are particularly important, they offer new avenues in optoelectronic devices, e.g., to alter the properties graphene electrodes. Nanoscale electrical characterization is essential for potential applications monolayer molybdenum trioxide. We present conductive atomic force microscopy study an epitaxially grown 2D oxide layer on graphene-like substrate, highly oriented pyrolytic graphite (HOPG). were also investigated using X-ray photoelectron spectroscopy, (semi-contact contact mode), Kelvin probe microscopy, lateral microscopy. demonstrate mobility unpinned island under slight mechanical stress well shaping detachment with applied stimulation. Non-stoichiometric MoO3-x monolayers show heterogeneous behavior terms conductivity, which can be related crystalline domains defects structure. Different regions various I–V characteristics, correlated their susceptibility electrodegradation. In work, we cover existing regarding nanomanipulation nanocharacterization MoO3 monolayer.
