摘　　要：Transparent conducting materials(TCMs)have been widely used in optoelectronic applications such as touchscreens,flat panel displays and thin film solar cells.These applications of TCMs are currently dominated by n-type doped oxides.High-performance p-type TCMs are still lacking due to their low hole mobility or p-type doping bottleneck,which impedes efficient device design and novel applications such as transparent electronics.Here,based on first-principles calculations,we propose chalcogenide perovskite YScS3 as a promising p-type TCM.According to our calculations,its optical absorption onset is above 3 eV,which allows transparency to visible light.Its hole conductivity effective mass is 0.48 m0,which is among the smallest in p-type TCMs,suggesting enhanced hole mobility.It could be doped to p-type by group-Ⅱelements on cation sites,all of which yield shallow acceptors.Combining these properties,YSCS3 holds great promise to enhancing the performance of p-type TCMs toward their n-type counterparts.
