Layer engineered interlayer excitons
Qinghai Tan, Abdullah Rasmita, Si Li +6
Photoluminescence (PL) from excitons serves as a powerful tool to characterize the optoelectronic property and band structure of semiconductors, especially for atomically thin 2D t…
Directional massless Dirac fermions in a layered van der Waals material with one-dimensional long-range order
T. Y. Yang, Q. Wan, D. Y. Yan +13
Exotic properties in single or few layers of van der Waals materials carry great promise for applications in nanoscaled electronics, optoelectronics and flexible devices. The estab…
Two-dimensional antiferromagnetic Dirac fermions in monolayer TaCoTe
Si Li, Ying Liu, Zhi-Ming Yu +5
Dirac point in two-dimensional (2D) materials has been a fascinating subject of research. Recently, it has been theoretically predicted that Dirac point may also be stabilized in 2…
Hourglass Weyl loops in two dimensions: Theory and material realization in monolayer GaTeI family
Weikang Wu, Yalong Jiao, Si Li +3
Nodal loops in two-dimensional (2D) systems are typically vulnerable against spin-orbit coupling (SOC). Here, we explore 2D systems with a type of doubly degenerate nodal loops tha…
