Series-Parallel Equivalent Circuit of Heterostructure with Quantum Wells

Based on the topology of a heterostructure with quantum wells, its equivalent circuit is proposed in the form of a series connection of parallel RC-circuits describing the electrophysical properties of barrier layers and quantum wells. The scheme takes into account the properties of the process of delivery of carriers to the wells, the capture of charge carriers by them, their radiative recombination, and also the through current through the heterostructure. Expressions are obtained for finding the capacitance and resistance of a serial RC equivalent circuit, as well as expressions for calculating the active and reactive elements of the equivalent circuit.
