Latest Patents
Hanzen's notable patent, titled "Optical Switching Device", describes an innovative device that comprises a transparent substrate, a switching film made of a hydride compound of a trivalent transition or rare earth metal, and a palladium capping layer. The switching film has a thickness of 300 nm, while the capping layer measures 30 nm and is in contact with hydrogen. This optoelectronic device allows for the switching on and off of electric current through the switching film. The resulting Joule heating facilitates a rapid transition between a transparent trihydride state and an absorbing dihydride state. The reversible conversion between both states can be repeated multiple times, making it particularly useful for applications in controlling light beams or displays. Optional cooling of the switching film can be achieved with a Peltier element.
