Terahertz Electronic and Spin Currents in Wafer‐Scale Van der Waals Bi2Se3/WSe2 Heterostructures and Polymorphs

Advanced Materials, Volume 38, Issue 1, 2 January 2026.
Van der Waals heterostructures offer exciting possibilities for artificial materials with unique optical, electronic, and spintronic properties. However, their use in the terahertz (THz) range is limited due to material constraints. This study demonstrates scalable, large‐area, crystalline 2D heterostructures, combining topological insulators ...

Efficient Broadband Terahertz Generation by Above‐Band‐Gap Excitation of the Pyroelectric ZnSnN2

Advanced Optical Materials, Volume 14, Issue 1, 9 January 2026.
Photo‐induced THz emission from the pyroelectric semiconductor ZnSnN2 is studied. For above‐band‐gap excitation, an ultrabroadband THz pulse is generated covering the range from 1 to 30 THz without any spectral gaps. The THz‐generation efficiency is about three orders of magnitude higher than that from a standard THz source like ZnTe with a similar ...

Mid‐Infrared Intersubband Transitions in p‐Type SiGe Parabolic Quantum Wells

Advanced Optical Materials, Volume 14, Issue 3, 19 January 2026.
The design, growth, and characterization of hole‐doped Ge‐rich SiGe parabolic quantum wells exhibiting mid‐infrared intersubband transitions are reported. Structural analyses confirm the parabolic compositional profile, while optical spectroscopy supported by tight‐binding simulations demonstrates strong and temperature‐stable absorption up to room ...

Crystallization Modulation and Defect Passivation of Tin‐Based Perovskite Light‐Emitting Diodes Avoiding DMSO

Advanced Optical Materials, Volume 14, Issue 3, 19 January 2026.
Tin‐based perovskites offer a lead‐free alternative for perovskite light‐emitting diodes (PeLEDs) but suffer from poor performance due to uncontrolled crystallization and Sn(II) oxidation. Here, NH4SCN is introduced into a DMSO‐free precursor to regulate crystallization, suppress Sn(II) oxidation, and reduce defects, enabling pure‐red PeLEDs with an ...
