论文摘要
随着超薄膜技术成为无处不在的商品，透明的导体在紧迫需求中毫无疑问。由于当前的溶液依赖于非丰富元素，因此已经建议将钙晶（例如SRVO3和SRNBO3）作为下一代透明导体。但是，我们的AB-INITIO计算和分析见解表明，通过强电子相关性将血浆频率降低到可见频谱以下 - 最近提出的策略以一种价格：增强的散射，从而在等离子体边缘以上具有实质性的光学吸收。作为解决这一难题的一种方式，我们依靠孔掺杂，较大的带宽和与其他频段的分离来识别几个钙钛矿透明导体。
Transparent conductors-nearly an oxymoron-are in pressing demand, as ultra-thin-film technologies become ubiquitous commodities. As current solutions rely on non-abundant elements, perovskites such as SrVO3 and SrNbO3 have been suggested as next generation transparent conductors. Our ab-initio calculations and analytical insights show, however, that reducing the plasma frequency below the visible spectrum by strong electronic correlations-a recently proposed strategy-unavoidably comes at a price: an enhanced scattering and thus a substantial optical absorption above the plasma edge. As a way out of this dilemma we identify several perovskite transparent conductors, relying on hole doping, somewhat larger bandwidths and separations to other bands.
