The latter -- spincoated from a colloidal solution produced by LiF/HCl etching of Ti3AlC2 powders -- were 13 nm thick with an area of 6.8 mm2. The changes in the films exposed to hydrogen (H) and oxygen (O) plasmas in vacuum were analyzed by X-ray photoelectron spectroscopy. We find that the film resistivities can be switched reproducibly by plasma treatment between 5.6 $\mu$$\Omega$m (oxidized state) to 4.6 $\mu$$\Omega$m (reduced state). Both states show metallic like conductivity. In high vacuum, the film resistivity was 243 $\Omega$; when the relative humidity was 80{\%} the film resistance increased to 6340 $\Omega$, a 26 fold increase.}, note = {<p>The publication of this article was supported by the Publication Fund of the University of Duisburg-Essen.</p>}, note = {<p><em>RSC Adv</em>., 2017,7, 13097-13103. <a href="https://doi.org/10.1039/C6RA27505B">https://doi.org/10.1039/C6RA27505B</a></p> <p>First published on 24 Feb 2017</p>}, doi = {10.1039/C6RA27505B}, url = {https://duepublico2.uni-due.de/receive/duepublico_mods_00044004}, url = {https://doi.org/10.1039/C6RA27505B}, file = {:https://duepublico2.uni-due.de/servlets/MCRFileNodeServlet/duepublico_derivate_00043637/Roemer_Controlling_conductivity.pdf:PDF}, language = {en} }
