SiDB Simulation and Gate Design Demo

This project introduces SiDB gates that were designed using the Exhaustive Gate Designer. The SiDB gates have been optimized with several figures of merit in mind, including Operational Domain, Band Bending Resilience, and Critical Temperature. The following gates are designed and analyzed:

NOTE: For better visualization, change the notebook theme in settings from light to dark.

These gates adhere to the Bestagon scheme, and their file format is .sqd, compatible with SiQAD for opening and further exploration.

Comprehensive documentation on how to use all pyfiction functions is available here.

Software Packages

All SiDB software tools are seamlessly integrated within fiction and can be accessed via PyPI.

(venv) $ pip install mnt.pyfiction

The bindings can then be used in the Python project:

from mnt.pyfiction import *

Detailed documentation and examples are available at ReadTheDocs and here.

The SiDB gates are presented and analyzed in the sidb_gate_designs_and_analysis.ipynb notebook with respect to the Operational Domain, the Population Stability, and the Critical Temperature.

Physical Simulation Parameters

The SiDB gates are designed for the following physical parameters:

• Charge-transition energy (μ_-): -0.25 eV
• Relative Permittivity (ε_r): 5.6
• Thomas-Fermi screening length (λ_tf): 5 nm

However, we found their Operational Domains to be quite large; as such they might work at slight deviations from these parameters.
