Hysteresis-less and stable perovskite solar cells with a self-assembled monolayer

Communications Materials, 2020
Common issues facing perovskite solar cells are current-voltage hysteresis and degradation during illumination. Here, a self-assembled monolayer is applied to an SnO2 electron transport layer, helping to achieve hysteresis-less behavior and limited ...

Self-assembled monolayer-based blue perovskite LEDs. [PDF]

Sci Adv, 2023
Blue perovskite light-emitting diodes (LEDs) have shown external quantum efficiencies (EQEs) of more than 10%; however, devices that emit in the true blue—those that accord with the emission wavelength required for Rec. 2100 primary blue—have so far been

Temperature and pH endurable self-assembled camellia-like nanostructure achieved on zinc sheet with superamphiphobicity for fog harvesting

Heliyon, 2023
Easy-implement and low-cost fabrication of super-hydrophobic/super-oleophobic materials is of great significance for efficient fog harvesting. Herein, we propose a simple two-step procedure based on Cu/1-octadecanethiol (ODT) self-assembled monolayer ...

Writing self-assembled monolayers with Cs: Optimization of atomic nanolithography imaging using self-assembled monolayers on gold substrates [PDF]

, 2012
We report the results of a study into the factors controlling the quality of nanolithographic imaging. Self-assembled monolayer (SAM) coverage, subsequent postetch pattern definition, and minimum feature size all depend on the quality of the Au substrate

Septipyridines as conformationally controlled substitutes for inaccessible bis(terpyridine)-derived oligopyridines in two-dimensional self-assembly

Beilstein Journal of Nanotechnology, 2011
The position of the peripheral nitrogen atoms in bis(terpyridine)-derived oligopyridines (BTPs) has a strong impact on their self-assembly behavior at the liquid/HOPG (highly oriented pyrolytic graphite) interface.
