A new class of 2D materials called XMenes (cross-meens) are predicted based on the non-van der Waals bulk XAM (cross-AM) phase.
Significance and Impact
The new XMenes significantly broaden the landscape of traditional MXenes exfoliated out of a MAX phase. This new material’s landscape is particularly promising for energy conversion (hydrogen evolution reaction), storage (anode materials), and unconventional superconductivity.
