In a breakthrough for applied physics, North Carolina State University researchers have developed a magnetic semiconductor memory device, using GaMnN thin films, which utilises both the charge and spin of electrons at room temperature. This is a major breakthrough, as previous devices that used magnetic semiconductors (GaMnAs) and controlled electron spin were only functional at 100 K (or -173 Celsius). By controlling the spin of electrons, the new device represents a significant advance in semiconductor efficiency and speed...
