Surface-enhanced Raman scattering of Ag–Au nanodisk heterodimers
We report the fabrication of Ag–Au nanodisk heterodimers based on the modified on-wire lithography method and study their surface-enhanced Raman scattering (SERS) properties experimentally and theoretically. The effects ...
Nanoscale-controlled enzymatic degradation of poly(L-lactic acid) films using dip-pen nanolithography
Proteinase K is patterned on poly(L-lactic acid) (PLLA) film by agarose-assisted dip-pen nanolithography. Lateral biodegradation at the nanometer scale on PLLA film is faster than vertical biodegradation. The height and ...
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 ...
