Recently, Johns Hopkins University materials scientist who discovered a new use of conductive compounds. After specific treatment, this compound can be made of insulating film, and the general insulator different from the role of its insulation to prevent current flow rather than by induced current flow elsewhere, to achieve. Allegedly, this feature is expected to present the material thickness and power consumption display devices are substantially reduced. Research published in the latest issue of "Nature Materials" magazine.
This material is known as the soluble form of sodium aluminum deposition in transistor technology and other portable electronic reader devices have a wide range of uses. Howard is responsible for the study, Professor Katz said that this sodium β alumina has some very useful features: can liquid production means that by the template can be embedded easily and accurately into the printed circuit, convenient size volume production; and low voltage means that this film can be at very low voltage start, its only made of smaller display devices can drive the battery power.
This transparent film in the solid state, only 100 atoms thick, it is suitable for the growing popularity of e-readers and other portable devices screen. In addition, can also be used to make aircraft or vehicle has a display on the windshield.
Katz said that with the insulating properties of sodium β alumina is a remarkable discovery. The emergence of this compound for several years, has been seen as conductor, was also considered a possible battery components. Because of its unique arrangement of atoms, this material allows charged particles and two-dimensional plane from a position parallel to easily pass, and in the vertical plane oriented material or non-place, the current can not flow.
