We present a simulation of ballistic magnetotransport in a curved resonant quantum cavity, a non-planar two-dimensional (2D) electron system formed by partial release of the planar cavity under strain. A transfer-matrix technique originally due to Usuki and coworkers [Phys. Rev. B 52, 8244 (1995)] has been adapted to ensure the technique’s continued dependability at high magnetic fields, and accommodate the nonzero local curvature of the simulated system. Conductance in non-planar structures is found to be highly sensitive to the changes in the curvature, indicating their potential in NEMS and sensing applications.
