Mean-field theory of the uniaxial ferroelectric smectic A liquid crystal phase
Aitor Erkoreka, Minjung Huang, Satoshi Aya +1
Following the groundbreaking discovery of the ferroelectric nematic liquid crystal phase (NF), a series of closely-related new polar phases have also been found. An especially inte…
Constraining the value of the dielectric constant of the ferroelectric nematic phase
Aitor Erkoreka, Josu Martinez-Perdiguero
Ferroelectric nematic liquid crystals are currently being subject to a plethora of investigations since they are of great fundamental interest and could potentially foster promisin…
A molecular perspective on the emergence of long-range polar order from an isotropic fluid
Aitor Erkoreka, Nerea Sebastián, Alenka Mertelj +1
The ferroelectric nematic phase (N) has quickly become the most studied system in liquid crystal research. In this work, we investigate the origin of such polar struct…
Dielectric spectroscopy of a ferroelectric nematic liquid crystal and the effect of the sample thickness
Aitor Erkoreka, Josu Martinez-Perdiguero, Richard J. Mandle +2
The recently discovered ferroelectric nematic liquid crystals have been reported to exhibit very large dielectric permittivity values. Here, we report a systematic investigation of…
Development of a high-frequency dielectric spectrometer using a portable vector network analyzer
Aitor Erkoreka, Josu Martinez-Perdiguero
A simple and novel setup for high-frequency dielectric spectroscopy of materials has been developed using a portable vector network analyzer. The measurement principle is based on…
