Magneto-Optical Properties of Quantum Emitters in Diamond
Abstract
An active search for new emitters in large bandgap materials such as diamond or hexagonal Boron-Nitride has taken place over the last years with the purpose of enabling novel quantum applications. One of the methods for creating defects in hexagonal Boron Nitride consists of ion implantation with an ion gun or indirect ion implantation, technique in which an accelerated ion hits an atom in rest, which in turn is implanted into the matrix. Towards this goal the project had mounted an experimental setup for implanting defects into large bandgap materials. A masters in physics student accomplished this task. Once a defect is created, the characterization of its optical and magnetic properties is required. These properties are highly modulated by the interaction between the defect and the vibrations of the lattice in which it is embedded. In this regard, we have modeled the interaction between phonons and the electronic spin associated to defects founding a remarkable electron spin resonance suppression, an effect hypothesized in the past but never estimated. In addition, we have modeled how nearby nuclear spins to the electronic spin associated to the nitrogen-vacancy color center can be polarized using several methods and most importantly how these polarization schemes are affected by non-radiative transitions.
