(a) Definition of characteristic lengths for the w-structured NWires growing along the axis with a hexagonal cross section and two {1000} interfaces at the top and bottom, plus four side interfaces with a {0021} orientation, shown along with the assignment of the interface atoms to the respective interface plane. Top and side views of the first four members, even series: (b) X16 (i = 1), (c) X56 (i = 2), (d) X120 (i = 3) and (e) X208 (i = 4). For atom colours, see Fig. 5. |
