The quasi-one-dimensional material PdTeI exhibits unusual electronic transport properties at ambient pressure. Here, we systematically investigate both the structural and responses of to external pressure, through a combination electrical transport, synchrotron x-ray diffraction (XRD), Raman spectroscopy measurements. charge density wave (CDW) order in is fragile transition temperature TCDW decreases rapidly with application resistivity hump indiscernible when pressure increased 1 GPa. Upon further compression, zero resistance established above 20 GPa, suggesting occurrence superconductivity. Combined XRD data evidence that emergence superconductivity accompanied by pressure-induced amorphization PdTeI.
