Abstract A single crystalline Mg2Si film was formed by solid phase reaction (SPR) of a Si(111) substrate with an Mg overlayer capped with an oxide layer(s), which was enhanced by post annealing from room temperature to 100 ℃ in a molecular beam epitaxy (MBE) system. The thermal stability of the Mg2Si film was then systematically investigated by post annealing in an oxygen-radical ambient at 300 ℃, 450 ℃ and 650 ℃, respectively. The Mg2Si film stayed stable until the annealing temperature reached 450 ℃ then it transformed into amorphous MgOx attributed to the decomposition of Mg2Si and the oxidization of dissociated Mg.

Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
