Laboratory philosophy

Under the precise control of interface reaction, IRE laboratory aims at contribute human society.

Basic guideline 0f IREL

Under the precise control of interface reaction, IRE laboratory aims at contribute human society through the creation of a fundamental technology for economic consumption.of materials and energy.

Laboratory guide

High quality GaN group III nitrides epitaxial films on Si substrate are our target. The plasma assisted radio frequency molecular beam epitaxy (RF-MBE) growth using an interface reaction epitaxy by a MBE machine in a clean room of Doshisha University. IRE Laboratory invented a unique interface reaction epitaxial technique using a double buffer layer and an AlN on Si template for growth of GaN on Si substrate. IRE Laboratory is developing another growth method using interface control other than the MBE method and is supporting characterization of grown GaN filems.
