| Abstract |
The configurational thermodynamics of a pseudo-binary alloy SnSe<sub>1-<i>x</i></sub>S<sub><i>x</i></sub> in the <i>Pnma</i> phase is studied using first-principles cluster-expansion method in combination with canonical Monte Carlo simulations. We find that, despite the alloy having a tendency toward a phase decomposition into SnSe and SnS at 0 K, the two constituent binaries readily mix with each other to form random SnSe<sub>1-<i>x</i></sub>S<sub><i>x</i></sub> solid solutions even at a temperature below room temperature. The obtained isostructural phase diagram of SnSe<sub>1-<i>x</i></sub>S<sub><i>x</i></sub> reveals that the alloy is thermodynamically stable as a single-phase random solid solution over a whole composition range above 200 K. These findings provide a fundamental understanding on the alloying behavior of SnSe<sub>1-<i>x</i></sub>S<sub><i>x</i></sub> and bring clarity to the debated clustering tendency in this alloy system. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 26 June 2018.
All research outputs
#20,014,336
of 25,461,852 outputs
Outputs from Journal of Physics: Condensed Matter
#2,798
of 6,156 outputs
Outputs of similar age
#251,666
of 342,437 outputs
Outputs of similar age from Journal of Physics: Condensed Matter
#71
of 243 outputs
Altmetric has tracked 25,461,852 research outputs across all sources so far. This one is in the 18th percentile – i.e., 18% of other outputs scored the same or lower than it.
So far Altmetric has tracked 6,156 research outputs from this source. They receive a mean Attention Score of 2.0. This one is in the 47th percentile – i.e., 47% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 342,437 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 22nd percentile – i.e., 22% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 243 others from the same source and published within six weeks on either side of this one. This one has gotten more attention than average, scoring higher than 59% of its contemporaries.
