Image of the week: tuning silicene synthesis

Silicene, often seen as graphene’s silicon counter-part is the latest 2D synthesised crystal to receive the attention of the material and condensed matter communities. This week’s image comes from work by C Grazianetti et al 2015 J. Phys.: Condens. Matter 27 255005. Their paper looks at using post-deposition annealing temperature as an additional parameter to tune the structural properties of silicene phases.
