Breu explicació del projecte / Brief explanation of your project
In this project, we are investigating doubly-clamped SiNWs that have been defined using a rapid three-step mask-less process based on focused ion beam (FIB) gallium implantation, silicon etching and a high temperature annealing step, generating SiNWs with optimal electrical properties for device development.

By controlling or tuning the annealing step, it is possible to promote recrystallization and the formation of nanocrystals or quantum dots (<10 nm) embedded inside the nanowires. This opens the possibility to fabricate Single Electron or Hole Transistors useful for quantum computing and with potential applicability in bio-sensing. Single electron devices can be formed by a small conductive island (of dimensions or diameters equals or smaller than 10 nm) electrically insulated from source and drain electrodes by two small capacitances. As a result, discrete electron energy levels can be created. In SETs, few electrons (ideally a single electron) are enough to define a bit of information. This gives unprecedented sensitivity to low charge perturbations, what can be exploited for single molecule detection and for quantum computing.
