Description/Abstract
Electron spins in Si quantum dots (QDs) provide an attractive alternative to their GaAs conterparts due to their much longer spin relaxation times[1]. We realise a pair of SOI-based double quantum dot (DQD) transistors facing each other with only a 50nm separation via E-Beam lithography and high resolution HSQ resist. A VLSI compatible fabrication process is implemented allowing for future scalability in quantum systems. We propose a new method of single electron detection verified by Monte-Carlo based simulations making use of the periodicity in the charge stability diagram of a DQD.
