Controlling the alignment of blue phase liquid crystals is challenging. Here, electric-field induced phase transitions are exploited to control the crystal orientation of blue phase I, and applied to the fabrication of holograms with omnidirectional

Abstract This paper presents a straightforward, low-cost, and effective integration process for the fabrication of membrane gate thin film transistors (TFTs) with an air gap. The membrane gate TFT with an air gap can be used as the highly sensitive t

Blue phase (BP) liquid crystals, which self-assemble into soft three-dimensional (3D) photonic crystals, have attracted enormous research interest due to their ability to control light and potential photonic applications. BPs have long been known as

Controlling the crystallographic orientation of 3D photonic crystals is important as it determines the behavior of light propagating through the device. Blue phases self-assemble into unique soft 3D photonic crystals with chiral structures for circul

Crystal twinning is an intergrowth of two or more single crystals of the same species with specific crystallographic relations in their orientations. Here, we perform microscopic optical characterization of (211) twins in the three-dimensional liquid

We present a facile method to control the three-dimensional (3D) orientation of blue phase (BP) liquid crystals. The field-induced intermediate phases, focal conic and BP X, from electrically unwound homeotropic state induce the [001] crystal axis to

We have investigated the azimuthal orientation behavior of blue phase (BPI) lattice reoriented from the electrically unwound homeotropic state, and it was found that the azimuthal angle changes to align the [001] axis parallel to the easy axis on a u

Various approaches are being pursued to realize compact optical elements with the ability to manipulate light, but it is difficult to simultaneously achieve high reflectivity and the ability to see through the element. Here, we present a reflective c

A large-angle polarization volume grating (PVG) with circular-polarization selectivity is demonstrated using a three-dimensional chiral liquid crystal with simple cubic symmetry – the blue phase (BP) II. We confirm defect-free alignment of the BP c

Varicose veins have a substantial burden on individuals’ aesthetics and overall quality of life. The current body of research on Korean medical interventions for varicose veins is limited in Korea, and exploration into clinical trends is lacking.
