Abstract: The output characteristics of InGaAs/AlAs resonant tunneling diodes (RTDs) changes as a function of external stress, and this meso-piezoresistive effect can be used to measure stress.In this paper, two RTD-based strategies to measure stress, resonance frequency measurement and RTD-Wheatstone bridge measurement, are discussed.The experimental results show that the piezoresistive sensitivity of the RTD-Wheatstone bridge can be configured within a range of 3 orders with different bias voltages, and the maximum piezoresistive sensitivity is 4.782e-9Pa-1.
Key words: current-voltage characteristic, oscillation frequency, piezoresistive sensitivity, resonant tunneling diode, stress measurement
