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.
Plasmonic enhancement of photocurrent in MoS2 field-effect-transistor
The two-dimensional material, molybdenum disulfide (MoS2), has attracted considerable attention for numerous applications in optoelectronics. Here, we demonstrate a plasmonic enhancement of photocurrent in MoS2 ...
Facile growth of a single-crystal pattern : a case study of HKUST-1
In order to fabricate metal–organic framework (MOF) based devices, it is desirable to precisely position high-quality and mono-sized MOF crystals on supports. In this work, we demonstrate a facile solution procedure for ...
Triangular Ag–Pd alloy nanoprisms : rational synthesis with high-efficiency for electrocatalytic oxygen reduction
We report the generation of triangular Ag–Pd alloy nanoprisms through a rationally designed synthetic strategy based on silver nanoprisms as sacrificial templates. The galvanic replacement between Ag nanoprisms and H2PdCl4 ...
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 ...
Coating two-dimensional nanomaterials with metal-organic frameworks
We demonstrate the coating of various 2D nanomaterials including MoS2 nanosheets, graphene oxide (GO), and reduced graphene oxide (rGO) with zeolitic imidazolate frameworks (i.e., ZIF-8) via a facile procedure. Additionally, ...
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 ...
A solution-processed hole extraction layer made from ultrathin MoS2 nanosheets for efficient organic solar cells
Room-temperature solution-processed ultrathin 2D MoS2 nanosheets are integrated into organic solar cells as an efficient hole extraction layer. An enhanced power conversion efficiency of 8.11% is achieved, which is superior ...
