| Outline of Research at the Start |
1. Simulation of hybrid optomechanical cavities, made by a piezoeletric and a diamond/Silicon materials.
2. Fabrication of the designed cavities.
3. VNA measurements of the cavities phononic properties.

| Outline of Annual Research Achievements |
First, I worked on the simulations of a phononic nanocavity made of diamond and a piezoelectric material, where the latter serves to activate mechanical modes. This triggers color centers spin transitions, making the cavity work as a qubit.
As a second topic, I fabricated phononic crystals on silicon membranes (bought with the grant budget), those unit cells are designed via genetic algorithm. I also measured Brillouin light scattering spectra of these crystals, thus probing their phononic properties.
For a third study, I started the fabrication lithium niobate samples. Deposition of metal interdigital transducers through evaporation techniques was also successful. The metals bought with the grant budget serve to fabricate these type of structures, those scope is to launch acoustic waves.
