Tunnelling current-voltage characteristics of Angstrom gaps measured with terahertz time-domain spectroscopy
Quantum tunnelling becomes inevitable as gap dimensions in metal structures approach the atomic length scale, and light passing through these gaps can be used to examine the quantum processes at optical frequencies. Here, we report on the measurement of the tunnelling current through a 3-Å-wide meta...
