“…To our knowledge, only one highpressure investigation on the structural, magnetic, and electronic properties of CrCl 3 has been performed by Ahmad et al (2020) up to 40.9 GPa in a diamond anvil cell (DAC) under different hydrostatic environments by virtue of synchrotron X-ray diffraction (XRD), Raman spectroscopy, photoluminescence spectroscopy measurements, and first-principles theoretical calculations. 17 Their synchrotron XRD and Raman scattering results for CrCl 3 revealed an isostructural phase transition (IPT) at 11.0 GPa based on the discontinuities in volume and axial ratios, the mergence of M2 and M3 Raman peaks, the inflection points in the Raman shift, spacings in the Raman shift, and Raman full width at half-maximum (fwhm). Further, the photoluminescence spectroscopy and first-principles theoretical calculations results confirmed that the IPT belongs to a semiconductor-to-semiconductor phase transition, which is accompanied by a magnetic transformation from the ferromagnetic to antiferromagnetic phases.…”

High-pressure structural, vibrational, and electrical transport properties of CrCl 3 were investigated by means of Raman spectroscopy, electrical conductivity, and high-resolution transmission electron microscopy under different hydrostatic environments using the diamond anvil cell in conjunction with the first-principles theoretical calculations up to 50.0 GPa. The isostructural phase transition of CrCl 3 occurred at 9.9 GPa under nonhydrostatic conditions. As pressure was increased up to 29.8 GPa, CrCl 3 underwent an electronic topological transition accompanied by a metallization transformation due to the discontinuities in the Raman scattering and electrical conductivity, which is possibly belonging to a typical first-order metallization phase transition as deduced from first-principles theoretical calculations. As for the hydrostatic condition, a ∼2.0 GPa pressure delay in the occurrence of two corresponding transformations of CrCl 3 was observed owing to the different deviatoric stress. Upon decompression, we found that the phase transformation from the metal to semiconductor in CrCl 3 is of good reversibility, and the obvious pressure hysteresis effect is observed under different hydrostatic environments. All of the obtained results on the structural, vibrational, and electrical transport characterizations of CrCl 3 under high pressure can provide a new insight into the high-pressure behaviors of representative chromium trihalides CrX 3 (X = Br and I) under different hydrostatic environments.

Engineering Near-Infrared Light Emission in Mechanically Exfoliated InSe Platelets through Hydrostatic Pressure for Multicolor Microlasing

γ-indium selenide (InSe) is a van der Waals semiconductor and holds great potentials for low-energy-consumption electronic and optoelectronic devices. Herein, we investigated the hydrostatic pressure engineered near-infrared (NIR) light emission of mechanically exfoliated γ-InSe crystals using the diamond anvil cell (DAC) technique. A record-wide spectral tuning range of 185 nm and a large linear pressure coefficient of 40 nm GPa −1 were achieved for spontaneous emissions, leading to ultrabroadband microlasing spectrally ranging from 1022 to 911 nm. This high emission tunability can be attributed to the compression of the soft intralayer In−Se bonds under high pressure, which suppressed the band gap shrinkage by increasing the interlayer interaction. Furthermore, two band gap crossovers of valence (direct-to-indirect) and conduction bands were resolved at approximately 4.0 and 7.0 GPa, respectively, resulting in pressure-sensitive emission lifetime and intensity. These findings pave the pathways for pressure-sensitive InSe-based NIR light sources, sensors and so on.

“…We hypothesize that this dramatic change in magnetic behavior, which can be thought of as arising from a compression along the chain-axis, could result in novel piezomagnetic or magnetostrictive properties under high pressure similar to what has been observed in layered CrCl3 and CrI3. 64,67,68 Fig. 3 Experimental χT curves (χ being magnetic susceptibility per mol Cr) measured from 1.8 K to 300 K under external magnetic field of 1000 Oe, with corresponding fit to the BF model given by equation 1 (red).…”

The synthesis, structure, and magnetic properties of two novel, pseudo-1D chromium thiolate coordination polymers (CPs), CrBTT and Cr2BDT3, are reported. The structures of these materials were determined using X-ray powder diffraction revealing highly symmetric 1D chains embedded within a CP framework. The magnetic coupling of this chain system was measured by SQUID magnetometry, revealing a switch from antiferromagnetic to ferromagnetic behavior dictated by the angular geometrical constraints within the CP scaffold consistent with the Goodenough-Kanamori-Anderson rules. Intrachain magnetic coupling constants JNN of −32 K and +5.7 K were found for CrBTT and Cr2BDT3 respectively using the 1D Bonner-Fisher model of magnetism. The band structure of these materials has also been examined by optical spectroscopy and Density Functional Theory (DFT) calculations revealing semiconducting behavior. Our findings here demonstrate how CP scaffolds can support idealized low-dimensional structural motifs and dictate magnetic interactions through tuning of geometry and inter-spin couplings.
