As the keystones of molecular electronics, high-quality nanodielectric layers are challenging to assemble due strictest criteria for their reliability and uniformity over a large area. Here, we report strained poly(4-vinylphenol) monolayer, ready be stacked form defect-free wafer-scale nanodielectrics. The thickness nanodielectrics can precisely adjusted in integral multiples 1.2 nm thick PVP monolayer. By employing double cross-linking strategy, an exceptional dielectric performance is achieved with leakage current 10–7–10–8 A/cm2 at 2 MV/cm across low-k as thin 3.6 nm. Furthermore, obtained could laminated onto various substrates on demand via polydimethylsiloxane soft stamps, enabling its application organic field-effect transistors both bottom-gate top-gate configurations. This work represents pivotal development (opto-)electronic materials heralds emerging avenue exploration functional field nanoelectronics.

Abstract The surface-assisted assembly of DNA origami lattices is a potent method for creating molecular lithography masks. Lattice quality and kinetics are controlled by various environmental parameters, including the employed surface, temperature, ionic composition buffer, with optimized parameter combinations resulting in highly ordered that can span surface areas several cm 2 . Established protocols, however, employ times ranging from hours to days. Here, hexagonal at mica surfaces observed within few minutes using high-speed atomic force microscopy (HS-AFM). A moderate increase concentration enables this rapid assembly. While forming regular lattice takes 10 min 4 nM, time shortened about 6 nM. Increasing any further does not result shorter times, presumably because arrival diffusion-limited. Over short length scales up 1 µm, order independent concentration. However, larger microns, nM yields slightly better than lower higher concentrations. Therefore, be considered optimum lattices. These results thus represent an important step toward industrial-scale application origami-based
