PhD topic and brief description

  • My PhD project comprises the fabrication, investigation and analysis of atomically thin two-dimensional (2D) materials as mechanical resonators in a fiber-based micrometer-sized cavity optomechanical system operating in the near-infrared part of the spectrum. The nanomechanical resonators will be ultra-thin drums made from 2D van der Waals materials presenting a bandgap in the wavelength range of interest, such as hexagonal boron nitride or transition metal dichalcogenides (TMDCs). On the one hand, the low mass of these 2D materials results in high resonance frequencies in the MHz regime and large zero-point fluctuations, ideal for optomechanics experiments. On the other hand, their thin dimensions make them perfect samples for the geometrical restrictions that our small cavity imposes. Moreover, the ability to stack them layer-by-layer opens the possibility to create novel heterostructures with new properties and functionalities to be investigated.
