  We present the first experimental evidence for metallicity, superconductivity
(SC) and the co-existence of charge density waves (CDW) in the
quasi-one-dimensional material HfTe3. The existence of such phenomena is a
typical characteristic of the transition metal chalcogenides however, without
the application of hydrostatic pressure/chemical doping, it is rare for a
material to exhibit the co-existence of both states. Materials such as HfTe3
can therefore provide us with a unique insight into the relationship between
these multiple ordered states. By improving on the original synthesis
conditions, we have successfully synthesised single phase HfTe3 and confirmed
the resultant structure by performing Rietveld refinement. Using low
temperature resistivity measurements, we provide the first experimental
evidence of SC at ~1.4 K as well as a resistive anomaly indicative of a CDW
formation at ~82 K. By the application of hydrostatic-pressure, the resistivity
anomaly shifts to higher temperature. The results show that HfTe3 is a
promising new material to help study the relationship between SC and CDW.
