Atomic structure of metal-halide perovskites from first principles: The chicken-and-egg paradox of the organic-inorganic interaction

We just submitted our first paper on hybrid perovskites. Look it up on the arXiv: http://arxiv.org/abs/1602.08935)

Our paper "Atomic structure of metal-halide perovskites from first principles: The chicken-and-egg paradox of the organic-inorganic interaction" is now available on the arXiv preprint server:  http://arxiv.org/abs/1602.08935. We use density-functional theory to study the atomic structure of several hybrid perovskite materials. We identify two stable structures and analyse them in terms of organic-inorganic and van der Waals interactions. The stable structures result from a delicate interplay between the position of the organic cation and the deformation of the inorganic framework like in the chicken-and-egg paradox.

Who publishes our open access publications?

Researchers at Aalto and Helsinki Universities favor open access journals with author fees published by large publishers. Popular journals without author fees are often published by universities or societies.
