                         measurement shows that the work function (0) without electric 
                         field is about 3.9 W. The field-emission current-voltage 
                         measurements indicate a threshold voltage ranging from 8.97x10^(6) 
                         to 9.64x10^(6) V/m and a work function (phi) about.0.3 eV. These 
                         results show that boron doped diamond films exhibit a negative
