摘要: Tunnelling spectroscopy measurements were carried out on the mixed crystal to investigate change in density of states CDW state. The temperature dependences energy gap widths obtained. Experiments showed that flattening peak curve with increasing x corresponds decrease gap. A model was proposed which anomalous characteristics this system explained terms competition two conduction mechanisms associated metallic carriers and `excitonic' carriers.
