CHROMIUM DOPED DIAMOND-LIKE CARBON

摘要

A heterojunction is provided for spin electronics applications. The heterojunction includes an n-type silicon semiconductor and a hydrogenated diamond-like carbon film deposited on the n-type silicon semiconductor. The hydrogenated diamond-like carbon film is doped with chromium. The concentration of the chromium dopant in the chromium doped diamond-like carbon film may be configured such that the heterojunction has an increase in forward bias current ranging from about 50% to about 150% in a small magnetic field at about room temperature. The heterojunction has spin electronics properties at about room temperature.
