Atomistic Modeling of Nano Devices: From Qubits to Transistors
13 Apr 2016 | Online Presentations | Contributor(s): Rajib Rahman
In this talk, I will describe such a framework that can capture complex interactions ranging from exchange and spin-orbit-valley coupling in spin qubits to non-equilibrium charge transport in tunneling transistors. I will show how atomistic full configuration interaction calculations of exchange in donor qubits help to propose an improved two-qubit gate in silicon. I will also show how spin-orbit-valley coupling due to interface roughness affects the spin resonance frequencies and spin lifetimes in silicon quantum dots. Finally, I will show how atomistic transport simulations help to identify the best 2D materials and designs for tunnel transistors.
