Intelligent materials in future electronics

With the increasing demand for higher speed and performance of computers, a new concept of electron devices is indispensable for future electronics. Devices with intelligent materials meet such a demand and can simplify electronics, so that a system made of the devices can perform more complex functions close to those for the human brain and organisms. Intelligent materials are distinct from conventional materials in their characteristics, and they have the potential to become a dominant electronic-material in the future because of their various built-in functions. In this paper an important concept in the design of intelligent materials, called k-space engineering, is introduced. The k-space engineering, which manipulates the band structure of an existing material, is promising for future electron devices.<
