Evidence of Room Temperature Charge-Density Wave Behavior and Glass-like States in Pressed Pellets of Lightly Doped Poly (3-methyl thiophene)

摘要

We show room temperature charge-density wave (CDW) characteristics in d.c. and a.c. electric data in pressed pellets of lightly doped poly(3 methylthiophene). The possibility of a Peierls glass is discussed and metastables states are observed. D.C. and A.C. data also show a state with negative differencial resistance.
