“…Input parameters for simulating the nonlinear element's I-V characteristic are: simulated I-V characteristic of the element's RTHS (as "current-voltage" pairs), OCs' contact resistivity and space, NCAs' thickness, doping and cross-section space. Simulation algorithms and mathematical models used to simulate RTDs' electrical parameters are described in [14,15].…”

The impact of spacer layers’ thickness on the resonant-tunneling diode’s (RTD) current-voltage characteristic and operational parameters of the RTD-based subharmonic mixer was studied during the described research using the software package developed by authors to simulate the RTD’s functional parameters while mixer’s parameters were simulated using existing microelectronic CAD. The research has revealed that the main impact on both RTD’s I-V characteristic’s shape and operational parameters of the studied subharmonic mixers is made by the emitter spacer layer’s thickness while the collector spacer’s thickness’ variation is insignificant in both cases. Such, it is shown that by varying the emitter spacer’s thickness from a single monolayer to twice its nominal value it’s possible to alter the RTD’s peak current from 0,28 to 1,92 of its nominal value. spacer layer’s thickness deviation of ±1 monolayer has a noticeable effect on the studied mixer’s operational parameters, especially on its dynamic range.

“…The problem of time costs becomes especially acute when moving from the analysis problem to the problem of designing an NHS with given performance characteristics, based on an iterative optimization procedure. This problem acquires special significance at the stages of modeling technological errors and the kinetics of the currentvoltage characteristic due to degradation, which is provided for by the reliability assessment method based on the gradual failure model [11][12][13][14][15][16][17][18]. Thus, an urgent task is to develop a model based on the physics of current transfer and having a relatively small dimensional and time complexity.…”
