Abstract

Single layer two-dimensional CdSe nanosheets are explored theoretically, highlighting the role of the coordinating (and stabilizing) ligands. Four isomeric CdSe single sheets bonded to H atoms are studied (CdSeH(2) ), as are four similar sheets with NH(3) coordinated to the Cd atoms. These are quite corrugated, unlike the pristine sheets, and have a different stability order from their graphane analogs.
