Wb. Choi et al., FIELD-EMISSION FROM SILICON AND MOLYBDENUM TIPS COATED WITH DIAMOND POWDER BY DIELECTROPHORESIS, Applied physics letters, 68(5), 1996, pp. 720-722
Thin diamond layers have been formed on molybdenum and single-crystal
silicon field emitters using a dielectrophoresis coating method from a
suspension of diamond powder in a nonconducting fluid. Transmission a
nd scanning electron microscopy observation revealed a significant amo
unt of diamond on the tips. The average thickness of the deposited dia
mond layer depended on the applied bias and the immersion time. Field
emission from these diamond-coated emitters exhibited significant enha
ncement compared to the pure emitters. (C) 1996 American Institute of
