(a) Cell employed in the [CpTi(cot)]@Au optimization
having six lying and two standingcot molecules. Rows of molecules in the lying disposition are labeled 1, while rows presenting alternating standing and lying arrangements on the
surface are labeled 2A and 2B. Panels b–e depict the simulated,
left, and experimental STM images, right, of the [CpTi(cot)]@Au layer
as a function of the bias voltage, Vb.
Simulations: 4.5 × 4.5 nm2, Vb = −2 V (b), −1 V (c), +2 V (d), +3 V (e). Experiment:
5.3 × 3.9 nm2, It = 20pA, Vb = −2 V (b), −1 V (c), +1 V (d),
+2 V (e). Negative biases represent the sample’s filled states,
and positive biases represent the empty ones. The unit cell and row
labeling shown in (a) are marked as a guide to the eye.
