| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Singlecrystalline diamond is a candidate as long-distance spin transport materials. Since diamond possesses a wide bandgap of 5.47 eV, the injection of carriers from ferromagnetic metals is not easy. To form highly conductive layers on singlecrystalline diamond, a laser-induced surface doping technique was employed. 193-nm pulsed laser beams were irradiated onto a diamond plate immersed in boric acid which acts as a dopant source. The surface electrical conductivity increases with increasing laser fluence and number of laser shots. Furthermore, the conductivity increases with increasing temperature, which implies that the surface layer is semiconducting. The depth profile of boron in secondary ion mass spectra showed the incorporation of boron atoms into depths of 40 nm below the surface. | |
