Several physico-chemical effects and properties in the solid state involve nanoscale interactions between adjacent materials and morphologies. Arrays of binary nanostructures can generate intimate interactions between different sub-components, but fabricating binary nanostructures is challenging. Here, we propose a concept to achieve diverse binary nanostructure arrays with high degrees of controllability for each of the sub-components, including material, dimension and morphology. This binary…

TLDR
This work reports a general method of growing centimetre-scale, uniform membranes of BNSLs that can readily be transferred to arbitrary substrates, and demonstrates the construction of magnetoresistive devices by incorporating large-area B NSL membranes that clearly show that device magnetoresistance is dependent on the structure (stoichiometry) of the BNSS.

Morphological instability leading to formation of porous anodic oxide films.
TLDR
It is shown that patterns of pores with a minimum spacing are possible only within a narrow range of the oxide formation efficiency (the fraction of oxidized metal atoms retained in the film), which should exist when the metal ion charge exceeds two.
Structural diversity in binary nanoparticle superlattices
TLDR
It is demonstrated that electrical charges on sterically stabilized nanoparticles determine B NSL stoichiometry; additional contributions from entropic, van der Waals, steric and dipolar forces stabilize the variety of BNSL structures.
