Large-Scale Arrays of Single-Layer Graphene
"... ABSTRACT We fabricated large arrays of suspended, single-layer graphene membrane resonators using chemical vapor deposition (CVD) growth followed by patterning and transfer. We measure the resonators using both optical and electrical actuation and detection techniques. We find that the resonators ca ..."

Transverse vibration of single-layer graphene sheets
, 2011
"... We investigate the vibrational properties of zigzag and armchair single-layer graphene sheets (SLGSs) using the molecular mechanics (MM) approach. The natural frequencies of vibration and their associated intrinsic vibration modes are obtained. Vibrational analysis is performed with different chiral ..."

Insulating Behavior at the Neutrality Point in Single-Layer Graphene
- Physical Review Letters
, 2013
"... The fate of the low-temperature conductance at the charge-neutrality (Dirac) point in a single sheet of graphene is investigated down to 20 mK. As the temperature is lowered, the peak resistivity diverges with a power-law behavior and becomes as high as several Megohms per square at the lowest tempe ..."

Ultra-short Optical Pulse Generation with Single-layer Graphene
- Journal of Nonlinear Optical Physics & Materials
, 2010
"... Pulses as short as 260 fs have been generated in a diode-pumped low-gain Er:Yb:glass laser by exploiting the nonlinear optical response of single-layer graphene. The appli-cation of this novel material to solid-state bulk lasers opens up a way to compact and robust lasers with ultrahigh repetition r ..."

Magnetic Kronig-Penney model for Dirac electrons in single-layer graphene
, 907
"... Abstract. The properties of Dirac electrons in a magnetic superlattice (SL) on graphene consisting of very high and thin (δ-function) barriers are investigated. We obtain the energy spectrum analytically and study the transmission through a finite number of barriers. The results are contrasted with ..."
Single-layer graphene nanosheets with controlled grafting of polymer chains.
- Journal of Materials Chemistry,
, 2010
"... Single-layer graphene nanosheets (SLGNs) are prepared by reduction of well-exfoliated graphite oxide aided by a surfactant (sodium dodecylbenzene sulfonate, SDBS). Grafting density and polystyrene (PS) chain lengths are controlled by modulating the concentrations of diazonium compound and monomer d ..."

Crack propagation in pre-strained single layer graphene sheets
"... a b s t r a c t We use molecular dynamics simulations to delineate crack propagation speed as a function of the crack length and the axial prestrain in a single layer graphene sheet. A covalent bond between two carbon atoms is assumed to break when the bond length has been stretched by 100%. For a ..."

Buckling of a single-layered graphene sheet on an initially strained InGaAs thin plate Buckling of a single-layered graphene sheet on an initially strained InGaAs thin plate
"... Abstract The elastic buckling behavior of a defect-free single-layered graphene sheet deposited on a strained InGaAs substrate is investigated. Such a buckled sandwich structure can be formed by local etching of an initially strained InGaAs substrate. We numerically investigated the necessary buckl ..."
