“…This is why the P 3 peak is present in UV Raman spectrum but not detectable via visible-light Raman experiments. 33 Prior theoretical studies of monolayers 31 find a Raman active normal mode for both crystals between 530 and 550 cm −1 . However, as shown in Figures 2a,b, the silicon substrate also shows an intense peak at 520 cm −1 which masks Raman features originating from the MPX 3 crystals.…”

We report results of investigation of the phonon and thermal properties of the exfoliated films of layered single crystals of antiferromagnetic FePS 3 and MnPS 3 semiconductors. Raman spectroscopy was conducted using three different excitation lasers with wavelengths of 325 nm (UV), 488 nm (blue), and 633 nm (red). UV−Raman spectroscopy reveals spectral features which are not detectable via visible Raman light scattering. The thermal conductivity of FePS 3 and MnPS 3 thin films was measured by two different techniques: the steadystate Raman optothermal and transient time-resolved magnetooptical Kerr effect. The Raman optothermal measurements provided the orientation-average thermal conductivity of FePS 3 to be 1.35 ± 0.32 W m −1 K −1 at room temperature. The transient measurements revealed that the through-plane and in-plane thermal conductivity of FePS 3 are 0.85 ± 0.15 and 2.7 ± 0.3 W m −1 K −1 , respectively. The films of MnPS 3 have higher thermal conductivity of 1.1 ± 0.2 W m −1 K −1 through-plane and 6.3 ± 1.7 W m −1 K −1 in-plane. The data obtained by the two techniques are in agreement and reveal strong thermal anisotropy of the films and the dominance of phonon contribution to heat conduction. The obtained results are important for the interpretation of electric switching experiments with antiferromagnetic materials as well as for the proposed applications of the antiferromagnetic semiconductors in spintronic devices.

“…More importantly, the damage appeared as a 'double-lung' pattern, which cannot be predicted by small-aperture laser-induced damage tests. We find that the 'double-lung' damage is mainly due to transverse stimulated Raman scattering (SRS) effect [12][13][14][15].…”

A unique 'double-lung' laser-induced damage pattern of a large-aperture potassium dihydrogen phosphate (KDP) crystal is observed during a damage experiment carried out on a large-aperture laser system, which has not been predicted by damage tests on small-aperture laser systems. Investigations show that 'double-lung' damage results from transverse stimulated Raman scattering (SRS) and the non-uniform fluence and intensity distribution of transverse SRS leads to the 'double-lung' damage pattern.
