Electric-Field-Induced Charge-Transfer Phase Transition: A Promising Approach Toward Electrically Switchable Devices Export

@article{citeulike:6097224, abstract = {PMID: 19788300 Much research has been directed toward the development of electrically switchable optical materials for applications in memory and display devices. Here we present experimental evidence for an electric-field-induced charge-transfer phase transition in two cyanometalate complexes: Rb0.8Mn[Fe(CN)6]0.93·1.62H2O and Co3[W(CN)8]2(pyrimidine)4·6H2O, involving changes in their magnetic, optical, and electronic properties as well. Application of an electric field above a threshold value and within the thermal hysteresis region leads to a transition from the high- to the low-temperature phase in these compounds. A model is proposed to explain the main observations on the basis of a para-ferroelectric transition. Our observations suggest that this new concept of electrical switching, based on materials exhibiting charge-transfer phase transitions with large thermal hysteresis loops, may open up doors for novel electro-optical devices.}, author = {Mahfoud, Tarik and Molnar, Gaabor and Bonhommeau, Sebastien and Cobo, Saioa and Salmon, Lionel and Demont, Philippe and Tokoro, Hiroko and Ohkoshi, Shin-Ichi and Boukheddaden, Kamel and Bousseksou, Azzedine}, citeulike-article-id = {6097224}, citeulike-linkout-0 = {http://dx.doi.org/10.1021/ja9055855}, citeulike-linkout-1 = {http://pubs.acs.org/doi/abs/10.1021/ja9055855}, day = {21}, doi = {10.1021/ja9055855}, journal = {Journal of the American Chemical Society}, keywords = {applications, cooperativity, crystal, data\_storage, electronics\_molecular, experimental, spin\_crossover\_compound, spin\_transition, switch}, month = {October}, number = {41}, pages = {15049--15054}, posted-at = {2009-11-11 09:46:26}, priority = {0}, title = {Electric-Field-Induced Charge-Transfer Phase Transition: A Promising Approach Toward Electrically Switchable Devices}, url = {http://dx.doi.org/10.1021/ja9055855}, volume = {131}, year = {2009} }
