Electronic structure of hm-C(CN)3 nanosheets. a Photograph of the hm-C(CN)3 nanosheet film patterned with the Au line for the scanning Kelvin probe measurement. b Line-scan data show the Fermi level of hm-C(CN)3 at each position on the purple line in a. c Band structure for hm-C(CN)3. The position of the reduction level for H+ to H2 is indicated by the dashed blue line and the oxidation potential of H2O to O2 is indicated by the purple dashed line just above the valence band. The blue and pink arrows represent the CB and VB positions of hm-C(CN)3 nanosheets which acquired from the experiment. d Spin-resolved total density of state for hm-C(CN)3. The short pink dotted line indicates the Fermi level
