(a) Model of the cylindrical channel under study. (b) Channel-induced potential of (3) is plotted for the channel with  nm,  nm, and  C/m² (note: is symmetrical with respect to the sign of ); (c) the potential well (red-solid line, see the left and bottom axes) and the potential barrier (green-dashed line, see the right and top axes) for the potential in (b). The potential  mV in this case.
