The interaction of water with Si- and C- terminated beta-SiC(001) surfaces was investigated by means of ab initio molecular dynamics simulations. Irrespective of coverage, varied from 1/4 to 1 monolayer, we found that water dissociates on the Si-terminated surface, substantially modifying the clean surface reconstruction , while the C-terminated surface is non reactive and hydrophobic. Based on our results, we propose that STM images and photoemission experiments may detect speciﬁc changes induced by water on both the structural and electronic properties of SiC(001) surfaces.
