Strain dependence of photoluminescence and circular dichroism in transition metal dichalcogenides: a k.p analysis

Shahnaz Aas, Ceyhun Bulutay

Within a two-band $k\cdot p$ method we analyze different types of strain for the $K$ valley optical characteristics of a freestanding monolayer MoS${}_2$, MoSe${}_2$, WS${}_2$ and WSe$_2…
