Crystal structure characterization and SHG polarimetry. (a) RT XRD pattern on the flat plane of IrTe2 showing (00l) peaks only as indicated. (b) IrTe2 structure with enclosed black solid lines representing its unit cell and the ab plane at RT. (c) Experimental setup for the SHG polarimetry. (d) SHG polarimetry at RT in the co-polarized (XX) (black open circles) and cross-polarized (XY) (pink open squares) configurations with the solid lines representing the corresponding fits for the trigonal symmetry. The green solid line at \(\:\phi\:\) = 50° indicates the polarization setting under which thermal cycle data is taken.
