Abstract
Electron diffraction measurements revealed that the quasi-one-dimensional c ompound InxNb3Te4 (x = 0.40, 0.60, 0.90, 1.0) exhibits charge density wave (CDW) modulation below similar to 150 K. The CDW wave vectors were q = +/- (1/3a* + 1/3b*) + zc*, where z is 0.433, 0.440, 0.453, and 0.462 for x = 0. 40, 0.60, 0.90, and 1.0, respectively. The increase in z with increasing x was interpreted as arising from the increase in Fermi energy due to In inte rcalation.
