Frequency Characteristics and Analysis of Quantum Resonant Tunneling Diodes
量子共振隧穿二极管的频率特性与分析

Using a HP8510C network analyzer, S parameter of AlAs/InGaAs/AlAs resonant tunneling diodes (RTD) is measured.Through extracting the equivalent circuit parameters from curve fit,the resistive cut off frequency of the fabricated device is calculated(dc to 54GHz) and the factors of affecting frequency are analyzed.
