Switching and memory effects based on the deformation of the charge-density wave (CDW) in K[sub 0.3]MoO[sub 3] are demonstrated. The deformations, which greatly affect the CDW dynamic phase transition from creep phase to slide phase, can be set by an external electric field and be removed by photoexcitation. This property can be exploited to realize an electrically readable switch or memory device without incorporating any circuitry but two electrical leads. © 2002 American Institute of Physics.
