Solid-State Electronics Journal Paper featuring QTCAD (Volume #204, June 2023, 108626)

QTCAD featured in international paper "Understanding conditions for the single electron regime in 28 nm FD-SOI quantum dots: Interpretation of experimental data with 3D quantum TCAD simulations"

Dear QTCAD community and quantum technology developers,

We are proud to be published again in the selective and international Solid-State Electronics journa featuring new results obtained with QTCAD.

In this article, we have used our tool QTCAD® to study Coulomb blockade physics in a first-generation #stmicroelectronics 28 nm FD-SOI quantum dot #device and explained why the single-electron regime was impeded during experiments.  This work induced constructive review of the system architecture which will prepare grounds for a next generation of improved quantum-dot devices opening up for #future #quantumcomputers.

This new paper continues the previous work started last year with our partners from Institut quantique – Université de SherbrookeSTMicroelectronics FranceCNRS and Université Grenoble Alpes, and further validates the predictive performance of our software QTCAD® within an R&D environment involving advanced and qualified #semiconductor technology.

Stay tuned for the next QTCAD® #software release (v1.2) which will include streamlined and accelerated workflows for the calculation of lever arm matrices and charge stability diagrams in double quantum dot systems, and more!
