Electronic devices such as vacuum tubes and transistors transformed the 20th Century. The invention of the vacuum tube diode and triode in the early part of the century led to wireless communication and the golden age of radio entertainment. The invention of the transistor enabled personal electronics, such as the transistor radio, as well as the widespread use of digital computers. With the invention of the integrated circuit, the personal electronics that we now take for granted became possible. Progress in electronics was driven by making the fundamental electronic building block, the transistor, smaller and smaller. At the beginning of the 21st Century, transistor dimensions started to be measured in nanometers. The 21st century is the age of nanoelectronics and will be transformed by increasingly powerful electronic products. At the same time, new applications that apply nanoelectronics to challenges in health, the environment, and energy will be increasingly important. This talk is an introduction to the past, present, and future of nanoelectronics.
