Raman spectroscopy of epitaxial graphene on a SiC substrate
may speed up the application of graphene for future electronic devices. The interaction of EG and the SiC substrate is critical to its electronic and physical properties. In this work, the Raman
Solution-gated epitaxial graphene as pH sensor.
A solution-gate field effect transistor (SGFET) has been fabricated on few-layer graphene, pointing to the potential application of graphene in ultrafast and ultralow noise chemical or biological sensors.
Surface-energy engineering of graphene.
By using a low-power oxygen plasma treatment, the wettability of graphene is improved without additional damage, which can solve the adhesion issues involved in the fabrication of graphene devices.
Raman Studies of Monolayer Graphene: The Substrate Effect
Graphene has attracted a lot of interest for fundamental studies as well as for potential applications. Till now, micromechanical cleavage (MC) of graphite has been used to produce high-quality
Fabrication of NiO Nanowall Electrodes for High Performance Lithium Ion Battery
We report the fabrication of vertically aligned NiO nanowalls on nickel foils using a plasma assisted oxidation method. Electrochemical properties of as-synthesized NiO nanowalls were evaluated by
Monolayer MoSe2 grown by chemical vapor deposition for fast photodetection.
The fundamental understanding for the differences in optoelectronic behaviors between MoSe2 and MoS2 is provided and is useful for guiding future designs in 2D material-based optoeLECTronic devices.
Role of metal contacts in high-performance phototransistors based on WSe2 monolayers.
It is demonstrated that the contact plays an important role in TMD phototransistors, and barrier height tuning is critical for optimizing the photoresponse and photoresponsivity.
Spatially Resolved Electronic Structures of Atomically Precise Armchair Graphene Nanoribbons
The surface-assisted bottom-up fabrication of atomically precise armchair graphene nanoribbons with predefined widths, namely 7, 14- and 21-AGNRs, on Ag(111) as well as their spatially resolved width-dependent electronic structures are presented.
