In-plane Anisotropy of Quantum Transport in Artificial Two-dimensional Au Lattices
We
report an experimental observation and direct control of quantum
transport in artificial two-dimensional Au lattices. Combining the
advanced techniques of low-temperature deposition and newly developed
double-probe scanning tunneling spectroscopy, we display a two-dimensional
carrier transport and demonstrate a strong in-plane transport modulation
in the two-dimensional Au lattices. In well-ordered Au lattices, we
observe the carrier transport behavior manifesting as a band-like
feature with an energy gap. Furthermore, controlled structural modification
performed by constructing coupled “stadiums” enables
a transition of system dynamics in the lattices, which in turn establishes
tunable resonant transport throughout a wide energy range. Our findings
open the possibility of the construction and transport engineering
of artificial lattices by the geometrical arrangement of scatterers
and quantum chaotic dynamics
