Summary: | The enhancement in electrical transport properties of exfoliated individual RuO
NSs was systemically investigated for their application in flexible electronics and optoelectronics. Decoration of Ag NPs on the surface of the RuO
NSs provides donor electrons and dramatically increases the electrical conductivity of the monolayer RuO
NSs by up to 3700%. The n-type doping behavior was confirmed via Hall measurement analysis of the doped RuO
NSs. The layer number- and temperature-dependence of the conductivity were also investigated. Moreover, carrier concentration and mobility were obtained from Hall measurements, indicating that the undoped RuO
NSs had ambipolar transport and semi-metallic characteristics. Moreover, the Ag-doped RuO
NS multilayer films on polycarbonate substrates were demonstrated by the Langmuir-Blodgett assembly methods, showing one-third reduction in the sheet resistance and extraordinarily high bending stability that the change in the resistance was less than 1% over 50 000 cycles. |
