Resonant transport and electrostatic effects in single-molecule electrical junctions
Resonant transport and electrostatic effects in single-molecule electrical junctions
In this contribution we demonstrate structural control over a transport resonance in HS(CH$_{2}$)$_{n}$[1,4 - C$_{6}$H$_{4}$](CH$_{2}$)$_{n}$SH (n = 1, 3, 4, 6) metal - molecule - metal junctions, fabricated and tested using the scanning tunnelling microscopy-based $I(z)$ method. The Breit-Wigner resonance originates from one of the arene $\pi$-bonding orbitals, which sharpens …
