论文摘要
我们报告了对青铜Na $ _ {1.5} $（PO $ _ {2} $）$ _ {4} $（WO $ _ {3} $）$ _ {20} $的合并结构和电子属性的调查。由于电荷密度波的不稳定性，其低维结构和费米表面的大量重建使得该散装物质是自然的超级晶体，具有减少的载体和费米能量。因此，据报道，多层2D电子弱定位的特征，量子振荡的影响增强。以前仅在真正的低维材料和设备中观察到的这两个拮抗实体之间的交叉，由于其隐藏的2D性质，显示出在散装晶体中发生的。
We report an investigation of the combined structural and electronic properties of the bronze Na$_{1.5}$(PO$_{2}$)$_{4}$(WO$_{3}$)$_{20}$. Its low dimensional structure and possible large reconstruction of the Fermi surface due to charge density wave instability makes this bulk material a natural superlattice with a reduced number of carriers and Fermi energy. Signatures of multilayered 2D electron weak localization are consequently reported, with an enhanced influence of quantum oscillations. A crossover between these two antagonistic entities previously observed only in genuine low dimensional materials and devices, is shown to occur in a bulk crystal due to its hidden 2D nature.
