Abstract

Based on functional buildingblock with conducting slabs and transparent slabs, a new model was proposed in designing ptype Cubased chalcogenides, i.e.transparent conducting materials (TCMs) with layered structure. Under the guidance of the model, LaCuOTe and Sr3Cu2Sc2O5S2 are selected and studied as TCMs, taking into consideration of their layered structure from ［Cu2Te2］/［Cu2S2］ conducting slabs and ［La2O2］/［Sr3Sc2O5］ transparent slabs. The optical and transport properties of two compounds verify the validity and feasibility of the model in designing and finding novel TCMs. The two compounds show high conductivity of 1.65-2.9S·cm-1 and considerable wide bandgap of 2.3-3.1eV, indicating considerable high conductivity and high transparency.

Key words： p-type Cu/Q; transparent conducting materials; conductivity; layeredstructure; functional buildingblock
