Abstract
The work shows that electrical behaviour of nanocontacts between free-standing ZnO nanowires and catalytic Au particle used for their growth can switch from Schottky to Ohmic depending on the size of the Au particles in relation to a cross-sectional width of the nanowires. This change in transport b...
