Using first-principles simulations combined with many-body calculations, we show that two-dimensional free-standing quintuple-layer (QL) Bi2Se2Te is an inversion-symmetric monolayer expected to achieve spatially indirect exciton with large exciton radius, small exciton effective mass, and long exciton ...

The successful exfoliation of atomically-thin bismuth telluride (Bi2Te3) quintuple layer (QL) attracts tremendous research interest in this strongly anharmonic quasi-two-dimensional material. The thermal transport properties of this material are not well understood, especially the mode-wise properties and...
Layer-dependent magnetic property in a superconducting quintuple-layer nickelate La6Ni5O12 来自 arXiv.org 喜欢 0 阅读量: 5 作者:T Yoon,MJ Han 摘要: To investigate the detailed magnetic properties of a recently discovered superconducting nickelate Nd6Ni5O12, we performed the first-principles ...
Molecular beam epitaxyTopological insulator thin films on insulating SiO2 can be used in gate tunable devices, and have been prepared using exfoliation methods, but rarely with direct-growth methods. Here, we present our study to directly grow quintuple layer Bi2Se3 on insulating SiO2 using ...
. Undoped NdNiObelongs to a series of layered square-planar nickelates with chemical formula NdNiOand is known as the 'infinite-layer' (=) nickelate. Here we report the synthesis of the quintuple-layer (=5) member of this series, NdNiO, in which optimal cuprate-like electron filling (...

Herein, thickness‐dependent photoluminescence studies unveil ultrahigh (282‐fold) room‐temperature photoluminescence (visible) from 20 quintuple layer Bi2Te3 nanosheets (NSs) compared to 200 quintuple layer NSs, attributable to a significant bandgap opening. Intriguingly, considerable photoluminescence ...
However, the fermiology of the quintuple-layer nickelate is more two-dimensional-like than its infinite-layer counterpart, making this new superconducting quintuple-layer nickelate more cupratelike without the need for chemical doping.Harrison LaBollita...
