Giant intrinsic carrier mobilities in graphene and its bilayer

…, MI Katsnelson, F Schedin, DC Elias, JA Jaszczak… - Physical review …, 2008 - APS
We have studied temperature dependences of electron transport in graphene and its bilayer
and found extremely low electron-phonon scattering rates that set the fundamental limit on …

Naturally occurring graphite cones

JA Jaszczak, GW Robinson, S Dimovski, Y Gogotsi - Carbon, 2003 - Elsevier
Carbon, boron nitride, and other materials that form nanotubes are also able to form conical
shapes. Even though the potential applications of cone arrays as electron emitters and other …

Graphite: flat, fibrous and spherical

JA Jaszczak - Mesomolecules: from molecules to materials, 1995 - Springer
The paradigm for the structure of graphite is that of a staggered stacking of flat layers of
carbon atoms (Figure 6-1). Individual layers, sometimes referred to as graphene sheets, 1 are …
