A wide range of topics is covered in this book, from the basics to practical examples of the operation of the work function and band alignment. These two factors determine the electric properties at interfaces, such as the Schottky barrier height and ohmic contact. Basic physics is used to systematically explain how to adjust and measure the work function and how to modify the band alignment required for controlling work function in functional materials and electrodes. The methods introduced in the book help to improve device performance and to solve problems of controlling the voltage and the efficiency of devices in a great variety of applications, including electronic devices, optical devices such as displays, and energy devices such as solar cells and batteries. Understanding the technical methods necessary for controlling the work function and band alignment can help to solve problems such as non-ohmic contact at source-electrode and/or drain-electrode interfaces in MOS structures, which directly contributes to improving power saving and reducing heat generation in computers.weiterlesen
