Spintronic OLED Debuts
An organic light-emitting diode (OLED) whose intensity is mediated by electron spin rather than purely by electronic charge may usher in a new breed of organic displays that are cheaper, brighter, and controlled by magnetic fields (Science, DOI: 10.1126/science.1223444). Z. Valy Vardeny of the University of Utah and colleagues based their spintronic device, which emits orange light, on their previous development of . . .
