Research and development at this center
substances and materials
At this center, we are conducting research and development on a wide variety of substances in order to acquire the desired material technology.
First, semiconductors are a typical functional material. Semiconductors are also used as switches that control current by utilizing their electron transport properties, and as chemical sensors that identify substances. Semiconductors are also used for light emitting and light receiving, that is, in devices that emit various types of light, such as lighting and displays, as well as in light sensors and solar cells.Materials that emit light include fluorescent materials, which are materials with a light-emitting structure built into them, and optical materials, such as lenses. In addition, there is a method of imparting fine structure to materials to achieve optical and electronic functions. A typical example is nanostructures such as metamaterials, which can be called nanosized antennas.Additionally, the materials needed for electronics include insulating materials such as capacitors, packaging materials, and piezoelectric materials. Additionally, some substances perform chemical functions such as trapping molecules or transporting ions.
At this center, material development is progressing from a variety of perspectives, from the search for new substances that exhibit unprecedented high functionality to technologies for applying superior materials as devices.
We would like to introduce the research and development of semiconductors at this center, especially semiconductors focusing on electron transport.
