Enhancement of photogenerated electron transport in dye-sensitized solar cells with introduction of a reduced graphene oxide-TiO2 Junction
Reduced graphene oxide (rGO) serves as an efficient electron-transport channel between dye molecules and the electrode in a dye-sensitized solar cell due to the formation of an rGO–TiO2 Schottky barrier junction, which can ...
Transparent, flexible, all-reduced graphene oxide thin film transistors
Owing to their unique thickness-dependent electronic properties, together with perfect flexibility and transparency, graphene and its relatives make fantastic material for use in both active channel and electrodes in various ...
Solution-processed nanocrystalline TiO2 buffer layer used for improving the performance of organic photovoltaics
In this study, we use solution-processable crystalline TiO2 nanoparticles as a buffer layer between the active layer and aluminum cathode to fabricate the P3HT:PCBM-based bulk heterojunction (BHJ) organic photovoltaic (OPV) ...
Nucleation mechanism of electrochemical deposition of Cu on reduced graphene oxide electrodes
The nucleation mechanism of electrochemical deposition of Cu on reduced graphene oxide (rGO) electrodes has been systematically studied on the basis of the cyclic voltammetry, Tafel plot, and chronoamperometry. Our results ...
All-carbon electronic devices fabricated by directly grown single-walled carbon nanotubes on reduced graphene oxide electrodes
A simple method for fabrication of all carbon CNT-rGO devices was developed, where the individual long-aligned SWCNT directly grew by CVD to connect with rGO electrodes scratched by non-metal objects.
Fabrication of flexible, all-reduced graphene oxide non-volatile memory devices
A flexible, all reduced graphene oxide non-volatile memory device, with lightly reduced GO as an active layer and highly reduced GO as both top and bottom electrodes, is fabricated by a full-solution process and its ...
Three-dimensional graphene materials : preparation, structures and application in supercapacitors
Three-dimensional (3D) graphene materials (3DGMs) are of great importance due to their unique properties and practical applications. A number of 3DGMs with novel structures have been developed in recent years. This review ...
A universal, rapid method for clean transfer of nanostructures onto various substrates
Transfer and integration of nanostructures onto target substrates is the prerequisite for their fundamental studies and practical applications. Conventional transfer techniques that involve stamping, lift-off, and/or ...
Preparation and applications of mechanically exfoliated single-layer and multilayer MoS2 and WSe2 nanosheets
Although great progress has been achieved in the study of graphene, the small current ON/OFF ratio in graphene-based field-effect transistors (FETs) limits its application in the fields of conventional transistors or logic ...
Mechanical exfoliation and characterization of single- and few-layer nanosheets of WSe2, TaS2, and TaSe2
Single- and few-layer transition-metal dichalcogenide nanosheets, such as WSe2, TaS2, and TaSe2, are prepared by mechanical exfoliation. A Raman microscope is employed to characterize the single-layer (1L) to quinary-layer ...
