Abstract

The sheet resistance (R_sk) underneath ohmic Au-electrodes on hydrogen-terminated surface-conductive diamond (001) surfaces was examined by a special current-voltage measurement. It has been found that R_sk is about ~ 200 times larger than the sheet resistance, R_sh, in the open areas without Au-electrodes. The specific contact resistance, R_C, of ohmic Au-electrodes on H-terminated surface-conductive diamonds as determined by linear transmission line models must be corrected accordingly. As the results of this, R_C is suggested to be of the order of 1 × 10^{− 3} – 1 × 10^{− 4} Ωcm².
