High frequency and high voltage mode of deformed helix ferroelectric liquid crystals in a broad temperature range

Abstract
A new electrooptical mode was discovered in Deformed Helix Ferroelectric (DHF) liquid crystal cells. This mode appears, if the driving voltage frequency and amplitude are rather high. The electrooptical response time τ0, 1-0, 9 is practically independent on temperature in a very broad range but it strongly depends on the driving voltage frequency.
