Abstract Carbon nanotube (CNT) field effect transistors (CNFETs) show promise for the next generation VLSI systems due to their excellent scalability, energy efficiency, and speed. However, high leakage current is a drawback of large diameter CNTs (d

Graphene plasmonic resonators have been broadly studied in the terahertz and mid-infrared ranges because of their electrical tunability and large confinement factors, which can enable the dramatic ...

Patterning graphene into nanostructures enables the coupling of free space radiation to plasmons in graphene. These plasmons are highly tunable and have been used in such applications as tunable filters and chemical sensors in the THz and mid-infrare

Top-down subtractive lithography has previously been used to pattern graphene nanostructures which lack ideal properties due to (1) limited resolution and (2) disordered edges. Here, we introduce a method to convert such disordered edges into relativ

We show a large enhancement in the Raman signal from a highly polarizable molecule attached to single layer graphene. Through spatial mapping of the Raman signal and wavelength-dependent Raman measurements from a dipolar chromophore latched to a grap

Field-effect transistors (FETs) that are stretchable up to 50% without appreciable degradation in performance are demonstrated. The FETs are based on buckled thin films of polyfluorene-wrapped semiconducting single-walled carbon nanotubes (CNTs) as t

We investigate the critical methane concentration (CMC) during the atmospheric-pressure chemical vapor deposition (AP-CVD) of graphene on Cu from CH4. Above the CMC, graphene both nucleates and grows; below the CMC, it etches; while at the CMC, carbo

We demonstrate the fabrication and study of the structure-property relationships of large-area (1 cm(2)) semiconducting nanoperforated (NP) graphene with tunable constriction width (w = 7.5-14 nm), derived from CVD graphene using block copolymer lith

We have recently reported on the synthesis and characterization of a new form of nanostructured graphene that we call "nanoperforated graphene". Nanoperforated graphene is fabricated by etching a periodic array of nanoscale holes into atomic membrane
