Quantum Dot based Quaternion High Transport Transistor Technology.

CSEF · 2023 Physics & Astronomy Second Award

Overview

Transistors themselves have not fundamentally changed in decades, with all advances in the field focused on merely decreasing the size of transistors. This is a problem as soon it will be impossible to continue to shrink transistors further. Transistors have also been exclusively focused on binary, with research into alternative logical systems extremely limited. In this research, a commercially competitive multivalued transistor is created order to improve transistors fundamentally and avoid stagnation. A Quantum Dot Field Effect Transistor (QDFET) design was utilized as Quantum Dot’s (Qdots) promote tunneling through cladding layers, allowing for multiple stability regions. In order to design this QDFET, a novel Monte-Carlo optimization algorithm to efficiently design molecules with many atomic possibilities was developed. The Monte-Carlo algorithm was coupled with Density Functional Theory (DFT), to simulate many of the molecules. In addition, a Neural Network (NN) model to approximate DFT simulations for certain large-volume calculations was devised, combined with GPT-3. Through the use of the NN and Monte-Carlo algorithm, an Indium Antimonide/Silicon-based QDFET was discovered for usage as a next-generation multivalued transistor. A device was then fabricated and the Hall effect across a Qdot matrix was measured. This device was found to have electron mobility over three orders of magnitude ahead of other multivalued options and significantly higher efficiency. With electron mobility on par with mature commercial options and its incredible multivalued logic benefits, this work produces a QDFET with effective performance over ten-fold in excess of any conventional transistor, promising a revolution in chip technology and an escape from Moore’s Law, with widespread effects on all of computing.
