Abstract:
In the past four decades, we have witnessed quick and large growth of the semiconductor industry, and how it has driven advances in communication, energy, health care, and security. Now it becomes the indispensable technology of our society. This great success of electronic industries was attributed to continuous and aggressive downsizing of the metal–oxide– semiconductor field-effect transistors (MOSFET). Another important achievement was light emitting diodes (LED) and semiconductor lasers based on compound semiconductors, which resulted in 2014 Nobel Prize in Physics for the development of efficient blue GaN LEDs (Akasaki, Amano, and Nakamura). Here, widegap semiconductors, especially group-III nitrides, played an important role, and they are now ready to use for power electronics, which expected to give a large impact on our society again.
