摘要
Electric contacts formed on an n-type diamond film by means of the Ga ion implantation were studied. The implanted Ga contacts revealed Ohmic property at room temperature. Contact resistivity for the implanted Ga contacts formed on the diamond film with donor density of 3 x 10(18) cm(-3) was 4.8 x 10(6) Ohm cm(2). The value is more than one order smaller than that for conventional vacuum-deposited metal contacts on the same diamond film. This contact has enabled us to measure electric properties for relatively lightly doped n-type diamond films in a temperature range between room temperature and 600 degrees C.
