From Ohmic to Ballistic Transport in Oriented Graphite

N. García, P. Esquinazi, J. Barzola-Quiquia +2

In this work we show that for a quasi-2D system of size $\Omega$ and thickness $t$ the resistance goes as $(2\rho /\pi t)\ln (\Omega /W)$, diverging logarithmically with the size. Measurements in hig…
