Frequency splitting of chiral phonons from broken time reversal symmetry in CrI
John Bonini, Shang Ren, David Vanderbilt +3
Conventional approaches for lattice dynamics based on static interatomic forces do not fully account for the effects of time-reversal-symmetry breaking in magnetic systems. Recent…
Electronic structure of Humble defects in Ge and GeSi
Shang Ren, Hongbin Yang, Sobhit Singh +3
The group-IV diamond-structure elements are known to host a variety of planar defects, including {001} planar defects in C and {001}, {111} and {113} planar defects in Si and Ge. A…
Nonreciprocal directional dichroism at telecom wavelengths
K. Park, M. O. Yokosuk, M. Goryca +7
Magnetoelectrics with ultra-low symmetry and spin-orbit coupling are well known to display a number of remarkable properties including nonreciprocal directional dichroism. As a pol…
Vibrational properties of CuInP2S6 across the ferroelectric transition
Sabine N. Neal, Sobhit Singh, Xiaochen Fang +6
In order to explore the properties of a two-sublattice ferroelectric, we measured the infrared and Raman scattering response of CuInP2S6 across the ferroelectric and glassy transit…
Vibrational fingerprints of ferroelectric hafnia
Shiyu Fan, Sobhit Singh, Xianghan Xu +6
Hafnia (HfO2) is a promising material for emerging chip applications due to its high-k dielectric behaviour, suitability for negative capacitance heterostructures, scalable ferroel…
