Summary

[edit]
Description AFM images of regio-random poly(3-decylthiophene-2,5-diyl) (P3DT) adsorbed on the surface of hBN. a An overview height scan of P3DT assembled on hBN, scan rate 6.51 Hz, 1024 × 1024 px; inset shows lattice frequency shift image of hBN acquired in FM-AFM tapping mode, scan rate 39 Hz, 512 × 512 px; both images were acquired with the same Arrow UHF probe oscillating at fundamental frequency of 1.42 MHz. b A selected area from scan a showing individual PT molecules and low-contrast features associated with decyl side chains. c Profile along the line highlighted in a showing molecule-to-molecule separation of 1.95 nm. d, e Structural models for P3DT assembly on hBN with corresponding dimensions calculated using the AM1 semi-empirical method. f Ultra-high-resolution AFM height scan of three individual P3DT molecules. Image (f) was acquired using third eigenmode of Multi75Al-G probe oscillating at 1.255 MHz and a setpoint of 24 mV. Scan rate 19.5 Hz, 1024 × 1024 px
