AMANO, Hiroshi

The Center for Integrated Research of Future Electronics (CIRFE), established in October 2015, engages in lead­ing-edge electronics research-including research in the un­traversed area of devices with gallium nitride, carbon nano­-tube, SiC and other post-silicon materials-while also cultivating top-notch human resources to lay the foundations of the future electronics industry. CIRFE is divided into six sections, each staffed with instructors who serve as leading spe­cialists in their field, and equipped with outstanding research infrastructure. The Center’s fully integrated joint research and education system covers everything from basic scientific education on materials, measuring, devices, and applied systems through to the completion of student educational courses. Through research on energy-saving devices, an area in which very little experimentation has been carried out anywhere in the world, CIRFE strives to foster well-trained human resources who will lead the field of manufacturing in the twenty-first century.

Section / Group

Device Innovation Section

The Device Innovation Section aims to develop devices with new functions by establishing new crystal-growth methods and process development for cutting-edge electronics materials with a central focus on wide-bandgap semiconductors, such as gallium nitride and silicon carbide, and nanocarbon materials. A fully integrated research approach enables us to establish a unified process from crystal growth to device design, manufacturing, and assessment.

Crystal Growth

To realize gallium nitride semiconductor devices that will serve as the foundation of next-generation electronics, we carry out a wide variety of research from the growth of bulk crystals for use as substrates free of killer defects to the growth and processing of next-generation quantum structures and nanostructures.

Surface/Interface

The effective use of electric energy can markedly reduce worldwide power consumption and improve the performance of electrical equipment including electric vehicles. This is realized using power semiconductors. Various electrical products generate heat. For example, much electricity is used to remove the heat generated by computer servers used to support our networked society. Ceramic materials play a key role in suppressing such heat. The use of ceramic materials markedly reduces the amount of CO2 generated. In our laboratory, we are developing new crystal growth technologies using artificial intelligence, and we are realizing new crystal materials such as power semiconductors, ceramics, and nanoparticles using the developed technologies. We aim to build a sustainable society that meets the Sustainable Development Goals (SDGs).
