Ultrahigh electron mobility in suspended graphene [PDF]
, 2008 We have achieved mobilities in excess of 200,000 cm2 V −1 s−1 at electron densities of ∼2 ×1011 cm−2 by suspending single layer graphene. Suspension ∼150 nm above a Si/SiO2 gate electrode and electrical contacts to the graphene was achieved by a ...

Detection of individual gas molecules adsorbed on graphene. [PDF]
Nature Materials, 2006 The ultimate aim of any detection method is to achieve such a level of sensitivity that individual quanta of a measured entity can be resolved. In the case of chemical sensors, the quantum is one atom or molecule.

Raman spectroscopy of graphene under ultrafast laser excitation [PDF]
EPJ Web of Conferences, 2019 The out-of-equilibrium Raman response of graphene is addressed by pulsed laser excitation. Phonon spectrum is rationalized by revisiting the electron-phonon picture in the light of a transient broadening of the Dirac cone.

Water friction in nanofluidic channels made from two-dimensional crystals
Nature Communications, 2021 Flow through nanometer scale channels facilitates an unmasked study of water-surface molecular interactions. Here, Keerthi et al. show with conduits made from graphite and hexagonal boron nitride that strong hydrophobicity does not rule out enhanced ...
