The effect of elastic scattering centers on the current-voltage (I-V) characteristics of double barrier resonant tunneling diodes with transverse confinement is examined. It is shown that elastic scattering centers break the separation of variables condition, and allow transitions between states of different transverse confinement. The changes to the transmission coefficients through the structure due to elastic scattering in the well of a resonant tunneling device are modeled by using perturbation theory. It is shown that additional structure in the I-V characteristics may result.
