Assessment: Problem sheets (60%) and Final Oral Discussion (40%)
This course explores experimental techniques to fabricate and characterize quantum devices, with particular emphasis on systems based on individual electrons and individual spins.
1) How can we fabricate nano-devices? Growth techniques (evaporation, sputtering, molecular beam epitaxy). Lithography (optical, electron beam). Etching.
2) How can we characterize nanoscale devices? AFM, STM, SEM, TEM, optical microscopy
3) Quantum spintronic devices. Introduction to spins. Spin initialization and readout in different systems. Rabi oscillations, Ramsey interferometry, spin-echo. Spin coherence timescales. Examples from different platforms (quantum dots, nitrogen-vacancy centres in diamond).
4) introduction to superconducting devices. Basic elements of superconductivity, Josephson junctions, superconducting quantum interference devices.
