cutting-edge fabrication technique [1] or a gift of self-
organization phenomena [2–6]. Common expectation
that such nanostructures break through limitations of
current technology may rely on a fact that nano-scale
shapes affect wave-functions of relevant electron states.
However, a way of designing nano-shapes which deci-
sively affect the electron states and therefore are intrigu-
ing in science and useful in technology is lacking.
One of the unexpected but promising examples
