Population inversion and ultrafast terahertz nonlinearity of transient Dirac fermions in CdAs
Changqing Zhu, Patrick Pilch, Renato M. A. Dantas +7
Harmonic generation provides an efficient tool for the study of ultrafast nonlinear dynamics. We report on time-resolved optical-pump terahertz-harmonic-generation spectroscopic in…
Self-intercalation as origin of high-temperature ferromagnetism in epitaxially grown Fe5GeTe2 thin films
M. Silinskas, S. Senz, P. Gargiani +8
The role of self-intercalation in 2D van der Waals materials is key to the understanding of many of their properties. Here we show that the magnetic ordering temperature of thin fi…
Exciton-exciton Interaction in Monolayer MoSe from Mutual Screening of Coulomb Binding
Ke Xiao, Tengfei Yan, Chengxin Xiao +7
The potential for low-threshold optical nonlinearity has received significant attention in the fields of photonics and conceptual optical neuron networks. Excitons in two-dimension…
Li iontronics in single-crystalline T-Nb2O5 thin films with vertical ionic transport channels
Hyeon Han, Quentin Jacquet, Zhen Jiang +13
The niobium oxide polymorph T-Nb2O5 has been extensively investigated in its bulk form especially for applications in fast-charging batteries and electrochemical (pseudo)capacitors…
Magnetic Weyl Semimetal Phase in a Kagome Crystal
D. F. Liu, A. J. Liang, E. K. Liu +16
Weyl semimetals are crystalline solids that host emergent relativistic Weyl fermions and have characteristic surface Fermi-arcs in their electronic structure. Weyl semimetals with…
Triply degenerate nodal points in RERhGe (RE=Y, La, Lu)
Peng-Jie Guo, Huan-Cheng Yang, Kai Liu +1
As a new type of fermions without counterpart in high energy physics, triply degenerate fermions show exotic physical properties, which are represented by triply degenerate nodal p…
