This paper presents a novel method for the assessment of mechanical effects on trench-Hall devices based on a moment expansion combined with two-dimensional finite-element discretization. Analogously to plate theories, a truncated moment expansion of the equations in the transverse coordinate is used to approximate the three dimensional problem. The resulting limited set of two-dimensional problems is discretized by means of finite-elements. The parametrization of the procedure lends itself to the optimization of the device geometry, therefore representing a valuable tool for the designer.
