Obtained Nb<sub>2</sub>O<sub>5</sub> nanosheets were chemically intercalated with H<sup>+</sup> in order to improve their electrical conductivity. Then, their morphology and electrical properties were investigated at the nanoscale level with a combination of conductive atomic force microscopy (C-AFM), current sensing force spectroscopy atomic force microscopy (CSFS-AFM, or PeakForce TUNA), scanning tunneling microscopy, scanning electron microscopy, X-ray photoelectron spectroscopy, and Raman techniques. This allows us to probe the electrical properties of 10-20-nm Nb<sub>2</sub>O<sub>5</sub> nanosheets as well as the interfaces between the substrate and the fabricated Nb<sub>2</sub>O<sub>5</sub> nanocrystals providing direct comparison between the morphology and the electrical properties at the nanometer scale. It was also proven that chemical H+ intercalation can improve conductivity of Q2D Nb<sub>2</sub>O<sub>5</sub> nanostructures.</div> </div> <div class='row'> <div class='leftDiv labelDiv col-xs-4 col-sm-2 fullRecLabelEnglish'>Keywords : </div><div class='valueDiv leftDirection leftAlign col-xs-8 col-sm-10 fullRecValueEnglish'>Raman spectra; X-ray photoelectron spectra; atomic force microscopy; electrical conductivity; intercalation compounds; nanofabrication; nanostructured materials; niobium compounds; scanning electron microscopy; scanning tunnelling microscopy; semiconductor growth; sol-gel processing; surface morphology; wide band gap semiconductors; C-AFM; CSFS-AFM; Nb<sub>2</sub>O<sub>5</sub>; Q2D nanostructures; Raman techniques; X-ray photoelectron spectroscopy; chemical intercalation; conductive atomic force microscopy; current sensing force spectroscopy; electrical conductivity; electrical properties; exfoliation; morphology; nanocrystals; nanoscale thickness; peak-force TUNA; quasi2D semiconductor nanosheets; quasitwo-dimensional nanosheets; scanning electron microscopy; scanning tunneling microscopy; size 10 nm to 25 nm; sol-gel method; substrate interfaces; 2-D nanostructures; Conductive AFM; exfoliation; niobium oxide; sol–gel;</div> </div> <div class='row'> <div class='leftDiv labelDiv col-xs-4 col-sm-2 fullRecLabelEnglish'>fLanguage : </div><div class='valueDiv leftDirection leftAlign col-xs-8 col-sm-10 fullRecValueEnglish'>English</div> </div> <div class='row'> <div class='leftDiv labelDiv col-xs-4 col-sm-2 fullRecLabelEnglish'>Journal_Title : </div><div class='valueDiv leftDirection leftAlign col-xs-8 col-sm-10 fullRecValueEnglish'>Nanotechnology, IEEE Transactions on</div> </div> <div class='row'> <div class='leftDiv labelDiv col-xs-4 col-sm-2 fullRecLabelEnglish'>Publisher : </div><div class='valueDiv leftDirection leftAlign col-xs-8 col-sm-10 fullRecValueEnglish'>ieee</div> </div> <div class='row'> <div class='leftDiv labelDiv col-xs-4 col-sm-2 fullRecLabelEnglish'>ISSN : </div><div class='valueDiv leftDirection leftAlign col-xs-8 col-sm-10 fullRecValueEnglish'>1536-125X</div> </div> <div class='row'> <div class='leftDiv labelDiv col-xs-4 col-sm-2 fullRecLabelEnglish'>Type : </div><div class='valueDiv leftDirection leftAlign col-xs-8 col-sm-10 fullRecValueEnglish'>jour</div> </div> <div class='row'> <div class='leftDiv labelDiv col-xs-4 col-sm-2 fullRecLabelEnglish'>DOI : </div><div class='valueDiv leftDirection leftAlign col-xs-8 col-sm-10 fullRecValueEnglish'>10.1109/TNANO.2013.2265893</div> </div> <div class='row'> <div class='leftDiv labelDiv col-xs-4 col-sm-2 fullRecLabelEnglish'>Filename : </div><div class='valueDiv leftDirection leftAlign col-xs-8 col-sm-10 fullRecValueEnglish'>6522825</div> </div> <div class='row'> <div class='leftDiv labelDiv col-xs-4 col-sm-2 fullRecLabelEnglish'>Link To Document : </div><div class='valueDiv leftDirection leftAlign fullRecValueEnglish col-xs-8 col-sm-10'><a href='https://search.ricest.ac.ir/dl/search/defaultta.aspx?DTC=49&DC=85434' target='_blank'>https://search.ricest.ac.ir/dl/search/defaultta.aspx?DTC=49&DC=85434</a></div> </div> </div> <div class='leftDiv labelDiv leftAlign backLinkEnglish'><a href='javascript:history.back()'><img src='../CSS/Back.png' class='backImage' alt=$
