In this paper, we extend our previous work on the second-order multiscale discontinuous Galerkin (DG) method for one-dimensional stationary Schrödinger equations with oscillating solutions (Dong et al., 2016) to high order. We propose two types of high-order multiscale finite element spaces, and prove that the resulting DG methods with these spaces converge optimally with respect to the mesh size h in L 2 norm when h is small enough. Numerically we observe that these two multiscale DG methods achieve at least the second-order convergence without any resonance errors when h≳ ε and optimal high-order convergence when h≲ ε, where ε is the scale of the wave length. We also demonstrate their ability to capture highly oscillating solutions of the Schrödinger equation in the application of the resonant tunneling diode (RTD) model.
