WebFeb 23, 2011 · We study the influence of a finite Hall field E H on the Hall conductivity σ yx in graphene. Analytical expressions are derived for σ yx using the Kubo-Greenwood formula. For vanishing E H, we obtain the well-known expression σ yx = 4 (N + 1 / 2) e 2 / h.The inclusion of the dispersion of the energy levels, previously not considered, and their width, … The quantum Hall effect (or integer quantum Hall effect) is a quantized version of the Hall effect which is observed in two-dimensional electron systems subjected to low temperatures and strong magnetic fields, in which the Hall resistance Rxy exhibits steps that take on the quantized values See more The quantization of the Hall conductance ($${\displaystyle G_{xy}=1/R_{xy}}$$) has the important property of being exceedingly precise.
