Abstract

We have searched for photoinduced absorption in the quasi-one-dimensional charge-density-wave materials blue bronze, with an N M = 3 4 filled band, and trimethylammonium-iodide-TCNQ, with N M = 1 3. In analogy to conducting polymers with N M = 1 2, one expects to observe mid-gap states due to solitons, with charge (modulo e) Q = ± 2e M. We have observed no photoinduced absorption in either material, using both broad-band and monochromatic searches, giving upper limits on the product of the probability of soliton formation and the lifetime of the soliton.
