C + -implanted GaAs that the surfaces were encapsulated with 2×10 20 cm −3 As-doped a-Si:H films were annealed at temperatures of 850–1000 °C. Carriers were generated only in a shallower region than the projected range of the C + ions. The shee

Silicon that is heavily doped with arsenic was treated in a microwave hydrogen plasma at temperatures of 530-600 °C. This hydrogenation increased the carrier concentration in the surface region where the concentration of As exceeded about 2 x 10 20

The surface of GaAs implanted with 100 keV Mg + ions at a dose of 1 × 10 15 cm −2 was encapsulated with As-doped a-Si:H with a thickness of about 80 nm. The sheet carrier concentration in thermally annealed samples increased with an increase in th

We propose the Ni–W plating film as a mold material for the hot embossing of borosilicate glass. The lifetime of a Ni–W plating mold is important from a practical perspective. However, there have been no previous reports on the life of a mold. Co
