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.119-124engconducting polymerscharge-density wavesmetastable statesPeierls glassnegative differential resistanceEvidence of room temperature charge-density wave behavior and glass-like states in pressed pellets of lightly doped poly (3-methyl thiophene)Artigo10.1080/10587250210435WOS:000175887000018Acesso restrito
