Figure : Band alignment of ZnSb 2 O 6 compared against common TCOs. Having verified our computational predictions through single crystal growth and characterisation, we investigated the potential of ZnSb 2 O 6 as a transparent electrode by calculating its band alignment and comparing to existing TCOs, shown in Figure . Our calculations reveal an ionisation potential (IP) and electron affinity (EA) of 9.6 eV and 6.1 eV, respectively. Sb 5s states contribute strongly to the CBM, much like ns states in the other post-transition metal TCOs, but sit lower in energy due to the increased distance from the nucleus and improved shielding of effective charge by core electrons.
