How It Compares
Within the transition-metal dichalcogenides class.
Unlike the more common hexagonal transition-metal dichalcogenides such as MoS2 or MoSe2, ReSe2 crystallizes in a distorted structure that leads to unique anisotropic physical properties. This structural deviation from its siblings, including ReS2, grants it distinct optical and electrical behaviors that are highly sought after for directional device applications.
