Abstract:
A method for forming first and second linear structures of a first composition, said first and second linear structures meeting at right angles and being separated by a gap, said method comprising the steps of:providing an etchable crystalline layer having said first composition; growing first and second self-aligned nanowires of a second composition on a surface of said etchable crystalline layer, said first nanowire growing at right angles to said second nanowire, said first nanowire being separated from said second nanowire by a gap of less than 10 nm; and anisotropically etching portions of said etchable crystalline layer that are not under said first and second nanowires using said first and second nanowires as a mask, to form said first and second linear structures of said first composition.
