Organic Semiconductor Device for Converting Spin Current to Electric Current (IMAGE)
Caption
The upper part of this illustration shows the device, built on a small glass slide, that was used in experiments showing that so-called spin current could be converted to electric current using several different organic polymer semiconductors and a phenomenon known as the inverse spin Hall effect. The bottom illustration shows the key, sandwich-like part of the device. An external magnetic field and pulses of microwaves create spin waves in the iron magnet. When those waves hit the polymer or organic semiconductor, they create spin current, which is converted to an electrical current at the copper electrodes.
