• using the PSIA XE-70 scanning microscope working in contact mode. Budget Sensors monolithic silicon probes ContAl-G (resonance frequency 13 kHz, force constant 0.2 N·m−1) were used. The XEI®, PSIA and Gwyddion® image processing software allowed us to correct sample inclination and distortions caused by

• feature of the TG electronic structure is presence of the vHs. In Raman spectroscopy, the presence of the vHs yields the G-resonance [48]. It consists of a more than one order of magnitude enhancement of the G-band intensity when the excitation energy fits the vHs energy difference. Indeed, the domains
