Abstract The PS defect is obtained by replacing one S atom with one P atom in the wide-bandgap semiconductor MgS. Based on first-principles calculations, the formation energy, defect levels, and electronic structure of the PS defect in different charge states are evaluated. We predict that the neutral PS0 and positively charged PS+1 are the plausible qubit candidates for the construction of quantum systems, since they maintain the spin conservation during optical excited transition. The zero-phonon lines at the PS0 and PS+1 defects are 0.43 eV and 0.21 eV, respectively, which fall in the infrared band. In addition, the zero-field splitting parameter D of the PS+1 with spin-triplet is 2920 MHz, which is in the range of microwave, showing that the PS+1 defect can be manipulated by microwave. Finally, the principal values of the hyperfine tensor are examined, it is found that they decay exponentially with the distance from the defect site.

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.
