Abstract:
Crystal TaS2 nanobelt arrays were fabricated on Ta wafers by a two-step method. Field-emission measurements show that the nanobelt arrays are decent field emitters with a turn-on field of approximately 0.7 V microm(-1), a threshold field of approximately 2.1 V microm(-1), and a field enhancement factor of approximately 4.33 x 10(4).
