Influence of surface band bending on a narrow band gap semiconductor: Tunneling atomic force studies of graphite with Bernal and rhombohedral stacking orders
Regina Ariskina, Michael Schnedler, Pablo D. Esquinazi +7
Tunneling atomic force microscopy (TUNA) was used at ambient conditions to measure the current-voltage (-) characteristics at clean surfaces of highly oriented graphite sampl…
Multiple-excitation study of the double-resonance Raman bands in rhombohedral graphite
Sergio L. L. M. Ramos, Marcos A. Pimenta, Ana Champi
The double-resonance (DR) Raman process is a signature of all sp2 carbon material and provide fundamental information of the electronic structure and phonon dispersion in graphene,…
Identification of a possible superconducting transition above room temperature in natural graphite crystals
Christian E. Precker, Pablo D. Esquinazi, Ana Champi +11
Measuring with high precision the electrical resistance of highly ordered natural graphite samples from a Brazil mine, we have identified a transition at 350~K with 40~…
