MoSSe (Molybdenum Sulfide Selenide alloy)
MoSSe alloy is a semiconductor. We have many different types of MoSSe alloys available containing a different ratio S/Se: from an alloy with a low amount of sulfur (close to 2H-MoSe2) up to high amount of sulfur (close to 2H-MoS2). The layers are stacked together via van der Waals interactions and can be exfoliated into thin 2D layers. The Molybdenum Sulfide Selenide alloy belongs to the group-VI transition metal dichalcogenides (TMDC).
