Thickness-Dependent Spintronic Terahertz Emission in MBE-Grown PtTe: From Semiconductor to Type-II Dirac Semimetal
Rahul Sharma, Sylvain Massabeau, Armando Pezo +13
Spintronic terahertz (THz) emitters have established themselves as among the most practical broadband THz sources available, yet their performance remains fundamentally limited by…
An AI-driven robotic system for two-dimensional hetero-assemblies
Xiaoxi Li, Jinkun He, Haojie Liu +27
Nanomaterials stacked on-demand, such as rotationally assembled two-dimensional (2D) van der Waals (vdW) layered compounds, provides a versatile platform for quantum simulation and…
Rashba engineering at van der Waals interfaces
Rahul Sharma, Soumya Mukherjee, Fatima Ibrahim +26
Two-dimensional transition metal dichalcogenide (TMD) interfaces offer a versatile platform for studying emergent quantum phenomena and enabling novel device functionalities. When…
Frustrated out-of-plane Dzyaloshinskii-Moriya interaction and the onset of atomic-scale 3 magnetic textures in 2D FeGeXTe (X = Te, Se, S) monolayers
Rabia Caglayan, Louise Desplat, Sergey Nikolaev +5
We theoretically study the effect of in- and out-of-plane Dzyaloshinskii-Moriya interaction (DMI) on the magnetic ground states of two-dimensional (2D) FeGeXTe (X=Te, Se, S) mo…
Spin and Orbital Rashba response in ferroelectric polarized PtSe/MoSe/LiNbO heterostructures
Armando Pezo, Sylvain Massabeau, Filip MiljeviÄ +6
Recent studies using Terahertz Time-Domain Spectroscopy (THz-TDS) with spintronic emitters as a source have revealed distinct signatures of the Rashba effect. This effect, which ar…
Current-induced spin and orbital polarization in the ferroelectric Rashba semiconductor GeTe
Sergio Leiva-Montecinos, Libor VojáÄek, Jing Li +4
The Edelstein effect is a promising mechanism for generating spin and orbital polarization from charge currents in systems without inversion symmetry. In ferroelectric materials, s…
