Obstinate electrons 'ignore' assumptions and follow another path

The nanowires, which have a cross-sectional area of no more than one square nanometer (a nanometer is one millionth of a millimeter), are attached to a substrate made of the semiconductor germanium. The virtually defect-free nanowires are spaced at intervals of just 1.6 nanometers. This forces electrons to adopt one-dimensional behavior.
