Clue to generate electric current without energy consumption at room temperature

Posted · Add Comment

Researchers have identified the requirements for the development of new types of extremely low power consumption electric devices by studying thin films made of Cr-doped (Sb, Bi)2Te3. At extremely low temperatures, an electric current flows around the edge of the film without energy loss owing to ferromagnetism. The research group proved that the atoms of […]
