In this paper, the finite difference algorithm in non-orthogonal curvilinear coordinates and the fourth-order Runge-Kutta method are combined to study the electrostatic characteristics of the micro-pin field-emission transistor. The cathode in the calculation model is a Tower structure. In this paper, the relationship between the tip field strength and the geometry, electron trajectory and anode current density are given.
