Abstract
In-situ Ar+-ion etching process is used to extract the defect-induced ultrathin 2D-stanene/stanene-oxide structured nano-materials from transparent conducting tin-dioxide (SnOx) thin films by KRATOS SUPRA spectrometer measurement system. In each etch- cycle during in situ successive Ar+-ion sputtering process, x-ray photoelectron (XPS) and ultraviolet photoemission spectroscopy (UPS) were measured and confirmed the formation of different crystal structures of defect-induced 2D-stanene and/or 2D-stanene oxide ultra-thin films. In situ XPS and UPS spectral results confirmed the formation of different defect-induced oxidation states of “Sn” and their change of density of states, valence band maximum and work functions of the extracted defect-induced ultra-thin 2D-stanene/stanene-oxide films. During etching process (τetch = 0–4000 s) the thickness is changes from 200 nm (SnOx) → ≈2.5 nm (2D-Stanene). These results, further revealed with the ex-situ Raman spectra measurements, where we have observed that the 2D-stanene/stanene-oxide is extracted from SnOx thin films by this successive Ar+-ion etching process. This process provides an option to realize aggressively scaled nanostructure device-based 2D-stanene/stanene-oxide materials with high-precision control that could be useful for fabrication of future electronic devices.
