Nanolithography of single-layer graphene oxide films by atomic force microscopy
Atomic force microscopy-based nanolithography is used to generate the single-layer graphene oxide (GO) patterns on Si/SiO2 substrates. In this process, a Si tip is used to scratch GO films, resulting in GO-free trenches. ...
Centimeter-long and large-scale micropatterns of reduced graphene oxide films : fabrication and sensing applications
Recently, the field-effect transistors (FETs) with graphene as the conducting channels have been used as a promising chemical and biological sensors. However, the lack of low cost and reliable and large-scale preparation ...
Surface enhanced Raman scattering of Ag or Au nanoparticle-decorated reduced graphene oxide for detection of aromatic molecules
We report a method for fabrication of an efficient surface enhanced Raman scattering (SERS) substrate by combination of metallic nanostructures and graphene, which shows dramatic Raman enhancement and efficient ...
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 ...
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.
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 ...
Layer thinning and etching of mechanically exfoliated MoS2 nanosheets by thermal annealing in air
A simple thermal annealing method for layer thinning and etching of mechanically exfoliated MoS2 nanosheets in air is reported. Using this method, single-layer (1L) MoS2 nanosheets are achieved after the thinning of MoS2 ...
