AuSe (alpha phase Gold Selenide)

AuSe Gold Selenide AuSe (alpha phase) is a metal. The layers are stacked together via van der Waals interactions and can be exfoliated into thin 2D layers. α-AuSe belongs to the group-XI transition metal monochalcogenides.

The Gold Selenide crystals produced at HQ Graphene have the appearance of mm size needles and have a metallic appearance.
