Unveiling Lattice Dynamics and a Hidden Structural Transition in the 2D Ferromagnet AgVPSe via Raman Spectroscopy
Thi Hai Yen Pham, Po-hao Chang, Aidan C. Malloy +7
Transition-metal chalcophosphates (TMCs) are two-dimensional (2D) van der Waals materials supporting a broad range of electronic and magnetic properties. Among quaternary TMCs, AgV…
The Origin of the Observed Raman Peaks in α-MnTe
Nurul Azam, Syed Mohammad Shahed, Liam T. Schmidt +21
The Raman spectrum of the room-temperature altermagnet -MnTe is reported to contain unassigned peaks at 120(3) cm and 140(3) cm, absent from the predicted phonon s…
Transport Enhancement and In Situ Control of Electronic Correlation via Photoinduced Modulation Doping of van der Waals Heterostructures
Collin R. Sanborn, Son T. Le, Thuc T. Mai +7
Modulation doping, a well-established technique for traditional semiconductor heterostructures, is a promising approach for tailoring carrier concentration in 2D materials devices.…
Probing Magnetic Properties of RuO Heterostructures Through the Ferromagnetic Layer
Frank M. Abel, Subhash Bhatt, Shelby S. Fields +20
RuO has been proposed as the prototypical altermagnetic material. However, several reports have recently questioned its intrinsic magnetic ordering, leading to conflicting fi…
Accurate Angle-Resolved Raman Spectroscopy Methodology: Quantifying the Dichroic Edge Filter Effect
Tehseen Adel, Maria F. Munoz, Thuc T. Mai +5
Angle-resolved Raman spectroscopy (ARRS) is an effective method to analyze the symmetry of phonons and other excitations in molecules and solid-state crystals. While there are seve…
