摘要：

We report the effect of hydrostatic pressure on the resistivity anomaly in KMo6O17 resulting from charge-density-wave (CDW) formation. The rate of decay of the Peierls temperature with pressure is partial derivative T(P)/partial derivative p = -2 Kkbar-1 for p < 6 kbar and partial derivate T(P)/partial derivate p = + 10 K kbar-1 for p > 6 kbar. The observed behaviour is ascribed to two competing mechanisms. At low pressures, interlayer couplings and a stiffening of the lattice are involved. At higher pressures, intralayer couplings and a strong enhancement of the density of states at the Fermi level are responsible for the large increase of T(P) observed.
