ABSTRACT

The operation of Tunnel Field-Effect Transistors (TFETs) is based on quantum mechanical tunneling. In order to develop an intuitive understanding of TFETs, it is essential that readers are familiar with the basic concepts of quantum tunneling. In this chapter, we briefly describe the key elements of quantum mechanical tunneling that are relevant to understand TFETs. Readers are, however, advised to refer to the basic textbooks on quantum mechanics [1-3] to explore more on the physics of tunneling.
