A research group in Germany has discovered a semiconducting material that can switch its semiconducting properties -- turning from one type of semiconductor to another -- via a simple change in temperature. This intriguing behavior may make the material useful in efforts to create better performing integrated circuits, which form the backbone of almost all electronic devices.
