Spin Based Devices

In the previous chapter, we discuss devices that control the flow of electrons or holes by making use of an electrostatic potential (intrinsic or extrinsic). Charge carriers (electrons and holes) have an additional degree of freedom in the form of spin, which may be thought of as a net magnetic moment pointing in two opposite directions, which are taken as either up-spin (\(\uparrow \)-spin) or down-spin (\(\downarrow \)-spin). In this chapter, we discuss the spin dependent properties of materials and how one may use them in devices—an area of immense scientific and technological interest, known as Spintronics.
