We analytically calculate the charge profile and demonstrate a strong (macroscopic) charge accumulation along the boundaries of a micrometer-wide strip. This charge inhomogeneity is especially important in the ...<br/><img src="http://prb.aps.org/files/SuggestionPRB30x30.jpg" alt="PRB Editors' Suggestion"/><br/> [Phys. Rev.
