This paper addresses the capacitance-voltage (C-V) characteristics of heterodimensional Schottky diodes, in which the Schottky metal is placed in direct contact to a two-dimensional electron gas and the confined electron behavior directly dictates the device performance. We develop a novel quasi-2D model for the C-V characteristics of the device, by starting from a self-consistent solution of the Schrödinger and Poisson equations in the growth direction. The model is validated by contrasting
