Rtd theory of operation

WebJun 20, 2024 · A new analytical model for the current–voltage characteristic of a resonant tunneling diode (RTD) is presented herein, being derived from the basic integral of the Tsu–Esaki equation. The model is physics based and developed as a function of material parameters such as the effective mass, barrier heights, and Fermi levels as well as … WebThe residence time distribution (RTD) of a chemical reactor is a probability distribution function that describes the amount of time a fluid elements could spend inside the reactor. Chemical engineers use the RTD to characterize the mixing and flow within reactors and to compare the behavior of real reactors to their ideal models.
