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…
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…
Phonon-tunable THz magnonic emission in multiferroic heterostructures
Sylvain Massabeau, Amr Abdelsamie, Florian Godel +13
Collective excitations such as magnons and polar phonons provide natural access to the terahertz (THz) regime, but efficient generation and tunability remain elusive. Multiferroic…
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…
Terahertz time-domain signatures of the inverse Edelstein effect in topological-insulator|ferromagnet heterostructures
Genaro Bierhance, Chihun In, Enzo Rongione +14
Three-dimensional topological insulators possess topologically protected surface states with spin-momentum locking, which enable spin-charge-current interconversion (SCI) by the in…
Monolayer control of spin-charge conversion in van der Waals heterostructures
K. Abdukayumov, O. Paull, M. MiÄica +25
The diversity of 2D materials and their van der Waals (vdW) stacking presents a fertile ground for engineering novel multifunctional materials and quantum states of matter. This pe…
