Research output: Contribution to journalArticlepeer-review


We have measured the temperature dependence of Young's modulus (E) of the quasi-one-dimensional conductor Nb3Te4. ΔE(T) E0 increases its slope sharply at T1 ∼ 95K, the commensurate charge density wave (CDW) phase transition. The existence of hysteresis in T1 confirms that this transition is first-order. A more dramatic anomaly, with a dip in relative modulus of 3×10-3 has been observed at T2 ∼ 40K, which is possibly due to another (second-order) CDW phase transition. Peaks in the internal friction have also been observed at these temperatures, but they are two orders of magnitude smaller than the relative changes in E.
