Layered 2D crystals by design: optimisation of Sb${}_2$Te${}_3$-GeTe van der Waals superlattices

Janne Kalikka, Xilin Zhou, Giacomo Nannicini +1

Herein a genetic algorithm for optimising the design of layered 2D heterostructure is proposed. As a proof-of-concept it is applied to Sb${}_2$Te${}_3$-GeTe phase-change material super…
