Based on first-principles simulations and calculations, we explore the evolutions of crystal structure, electronic structure, and transport properties of quasi-two-dimensional layered $\mathrm{Pd}{\mathrm{S}}_{2}$ under compression by uniaxial stress and hydrostatic pressure. An interesting ferroelastic phase transition with lattice reorientation is revealed under uniaxial compressive stress, which originates from the bond reconstructions …
