| Research Abstract |
To investigate the properties of 4H-AlN/4H-SiC(11-20) heterojunction, heterojunction field-effect transistors(HFET) and Hall devices with the heterojunction were fabricated. In the fabrication process for these devices, SiC related processes, that is, epitaxial growth of SiC and ion implantation to SiC were completed. However, there still remain several challenges in epitaxial growth of AlN and post AlN growth process, resulting that the device fabrication is incomplete. We will try to resolve the challenges and complete the devices. We believe that characterization of these devices lead to clarification of the heterojunction properties.
