We present experimental evidence and a corresponding theory for the ferroelectric transition in the family of quasi-one-dimensional conductors (TMTTF)2X. We interpret this new transition in the frame of the combined Mott-Hubbard state taking into account the double action of the spontaneous charge disproportionation on the TMTTF molecular stacks and of the X anionic potentials.
我们给出了准一维导体(TMTTF)2X族中铁电转变的实验证据及相应理论。我们在考虑TMTTF分子链上自发电荷歧化和X阴离子势的双重作用的组合莫特-哈伯德态框架内解释这种新转变。
