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.…
Ultraviolet Exciton-Polaritons in Silver Phenylthiolate
Bongjun Choi, Bonnie Chen, Thuc T. Mai +8
Ultraviolet (UV) exciton-polaritons (EPs) enable nonlinear optics, polaritonic lasing, and polariton-mediated photochemistry in the short-wavelength regime, yet progress has been l…
Raman and Terahertz Spectroscopy of Low-Frequency Chiral Phonons in Amino Acids
Rahul Rao, Won Jin Choi, Joseph M. Slocik +6
Chiral phonons are mirror-symmetric vibrations that correspond to twisting and rotational motions of atoms. In chiral biomolecules, they correspond to low-energy terahertz (THz)-ra…
Coupled Ferroelectricity and Phonon Chirality
Xiang-Bin Han, Cong Yang, Rui Sun +10
The ability to control chirality and chiral phonons offers a route to manipulate the direction of spin and angular-momentum transport. In materials with rigid structural chirality,…
Weyl Magnons in the Non-Coplanar Antiferromagnet MnTe
Ahmed E. Fahmy, Archibald J. Williams, Yufei Li +9
Using a combination of band representation analysis, inelastic neutron scattering (INS), magneto-Raman spectroscopy measurements, and linear spin wave theory, we establish that the…
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…
