New type of liquid crystal identified; Holds promise of faster, lower priced liquid crystal displays

15.06.2004


A new type of liquid crystal - recently discovered by a research team that includes a Kent State University professor - holds the promise of faster liquid crystal displays at a lower price.



A new liquid crystal phase – the biaxial nematic liquid crystal - which is likely to revolutionize the liquid crystal display technology, has been discovered by three researchers, Dr. Satyendra Kumar, professor of physics at Kent State; Dr. Bharat R. Acharya, of Platytus Technologies, Madison, WI; and Dr. Andrew Primak, of Pacific Northwest National Lab, Richland, WA.

Currently, the liquid crystal displays used in most laptops and televisions make use of the uniaxial nematic liquid crystal. It is predicted that the use of biaxial nematic liquid crystals will make these products more than 10 times faster and will allow for cost-saving measures.


The existence of the biaxial nematic liquid crystal was predicted 34 years ago by IBM’s Thomas J. Watson Research Center in Yorktown Heights, N.Y.

However, according to Acharya, "There was no evidence of the existence of biaxial nematic liquid crystals made of single molecules until recently. Other types of more complex micellar biaxial liquid crystals were found previously by Kent State researchers, but, until now, none had the right optical properties for use in displays and photonics devices."

A paper reporting how the researchers used small-angle X-ray diffraction technique to discover the biaxial nematic liquid crystal appeared in the April 9 issue of the prestigious Physical Review Letters. Kent State researchers also presented their initial evidence in 2000 at the March meeting of the American Physical Society. This research will be presented by Kumar in an invited talk at the International Liquid Crystal Conference in Slovenia on July 6, 2004.

Im Focus: Quantum optical sensor for the first time tested in space – with a laser system from Berlin

For the first time ever, a cloud of ultra-cold atoms has been successfully created in space on board of a sounding rocket. The MAIUS mission demonstrates that quantum optical sensors can be operated even in harsh environments like space – a prerequi-site for finding answers to the most challenging questions of fundamental physics and an important innovation driver for everyday applications.

According to Albert Einstein's Equivalence Principle, all bodies are accelerated at the same rate by the Earth's gravity, regardless of their properties. This...

Im Focus: Interfacial Superconductivity: Magnetic and superconducting order revealed simultaneously

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.

While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
