Objective
We will realize and model nanoscale Josephson field effect devices that will operate as single-electron hybrid super-conducting nanoswitches. We will create three-terminal S-QD-S devices, "Josephson quantum dots" (JDOTs), where the super-conducting (S) source and drain contacts are connected by a quantum dot (QD) operating in the desirable but unexplored quantum confined (molecular) regime. Nanogates will enable very sensitive super-current tuning by controlling the QD charge state with single electron accuracy.
By learning how to switch Josephson currents on/off simply by adding/removing a single electron, we will create a very sensitive coherent switching device. Compared to the state of the art, our JDOTs should allow for larger currents, higher switching sensitivity, lower power consumption, and scalability from 100nm down to 1nm. They could thus constitute elementary building block for non-dissipative nanoelectronics.
To ensure success, we will explore and compare both carbon nanotube and semiconductor nanostructures. We will focus on the Coulomb-blockade and Kondo regimes and study on/off switching behaviour, interplay between charge, spin, and super-conducting correlations, and non-equilibrium effects.
Our objectives are:
1) provide a proof-of-concept under ideal operating conditions
2) decide on which of the developed nanostructures offers the best potential for future applications.
HYSWITCH brings together some of the leading experimental and theoretical groups in this field. It is built on a well-recognized platform of innovative achievements by the partners, which warrants the immediate undertaking of this high risk/high gain project. The new functions that may be achieved with the proposed devices can hardly be imagined within the existing paradigm of semiconductor epitaxy. This window of opportunity must be pursued vigorously if similar US-based efforts are not to leave the EU behind.
