We study theoretically the charge separation in a planar array ofsemiconducting nanotubes (NTs) of length, 2h, placed in external electricfield, F, parallel to their axes. By employing the conformal mapping, we findanalytically the exact distribution of the induced charge density for arbitraryratio of the gap, E_g, and the voltage drop, eFh, across the NT. We use theresult obtained to (i) trace the narrowing of the neutral strip at center ofthe NT with increasing F; (ii) analyze the polarizability of the array as afunction of E_g; (iii) study the field enhancement near the tips.Comment: 9 pages, 5 figures, RevTe
