Matching conditions for the envelope function in the effective mass approximation are determined based on the feasibility of exactly solving the effective mass Schrödinger equation. The transmission and reflection probabilities for these conditions at an abrupt heterojunction are determined for a step mass and step potential and an alternative description of transport across the heterojunction based on the interplay between discontinuities of the quantum force and the effective mass is discussed.
