By using DFT calculations, the electrical properties of a SnSe2 monolayer with p-type and n-type doping in addition to isoelectronic doping are investigated. A SnSe2 monolayer with p-type conductivity cannot be obtained, whereas n-type conductivity in this monolayer can be achieved by Br doping. Isoelectronic doping does not change the intrinsic semiconducting features of the SnSe2 monolayer. More information can be found in the Full Paper by Y. Huang et al. on page 375 in Issue 3, 2016 (DOI:10.1002/cphc.201501034).
