Ultrafast All-Optical Terahertz Switchable Modulation Using Van Der Waals Fe4GeTe2/Bi2Te3 Heterostructures (Advanced Optical Materials 26/2025)
Optical-Pump Terahertz-Probe Spectroscopy
In article 10.1002/adom.202500951, Zuanming Jin, Tianxiao Nie, Yan Peng, Yiming Zhu, and co-workers investigate ultrafast all-optical THz switchable modulation in two-dimensional van der Waals Fe4GeTe2/Bi2Te3 heterostructures using optical pump-THz probe (OPTP) spectroscopy. By comparing the OPTP results of Fe4GeTe2/Bi2Te3 with those of single-layer Fe4GeTe2 and Bi2Te3 films, it has been determined that both interface carrier accumulation and thermal effects contribute to conductivity switching, indicating potential for advanced opto-spintronic devices.
