Photocontrol of dynamic phase transition in the charge-density wave material K(0.3)MoO(3).
A photoinduced effect has been studied in the quasi-one-dimensional conductor K(0.3)MoO(3). A weak photoexcitation of the sample can drastically affect the dynamic phase transition of the charge-density wave (CDW) motion from slide to creep. The origin of the photoeffect is attributed to a local destruction of the CDW which leads to the photoinduced phase slip and the redistribution of the CDW phase.
