Description
The one-dimensional (1D) strongly correlated BaVS3 undergoes a series of unexplained phase transitions. Among them it undergoes a metal-insulator (MI) transition associated with a 2kF=c*/2 charge density wave (CDW) instability. We show that this CDW ground state is very sensitive to chemical substitutions and/or sulfur deficiency. Substitutions of V with ∼2% of Nb, Ti or Ba with ∼2% K in probably sulfur deficient samples leads to a completely different ground state. This ground state is characterized by a short range structural modulation with the incommensurate wave vector qS=(13130.21)H, which could be due to a CDW taking place in a differently filled dz2 band
