Summary
Did you know that today’s smart phones have computing power comparable to supercomputers of 25 years ago? Nanotechnology, which designs the properties of solids by precisely controlling the arrangement of atoms and molecules, plays an important role in the development of cutting-edge semiconductor and magnetic elements that support this rapid development of the information society. There is a worldwide competition to discover new physical phenomena, develop elements that work based on new principles, and develop extreme measurement technologies and theories that support these discoveries. Similarly, cutting-edge semiconductor and magnetic material technologies are used in solar cells, which are a source of reusable energy for realizing a sustainable world, and in electric power devices that convert the resulting electric power into voltage for use in electric vehicles.
These semiconductor and magnetic devices will continue to play a leading role in supporting the advanced information society and solving energy problems. The goal of this major is to foster engineers and researchers who can develop new electronic elements from a broad perspective, or develop and construct measurement methods and theories to support them, by learning the fundamentals of solid-state physics, electronics (transistors, semiconductor lasers, solar cells, integrated circuits, magnetoresistive elements, etc.), and other nanotechnologies. The goal of the program is to foster engineers and researchers who can develop new electronic devices from a broad perspective or develop and construct measurement methods and theories to support them.
