Abstract
We have analyzed the effect of disorder in both the well and barriers of a resonant tunneling diode (RTD). If the disorder is limited solely to the barriers, a good peak-to-valley ratio (PVR) is expected. We describe a general guideline relating the PVR to the bulk mobility and effective mass of the well material of an RTD. We compare the effects of correlated versus uncorrelated disorder on the valley current. We discuss why interband tunnel devices such its the Esaki diode are more robust than RTDs in the presence of disorder
