CEG's The Research Connection

Description: SUNY Poly Professor Kathy Dunn and her research team are using photons, electrons and ions to uncover relationships between crystalline defects and chemical inhomogeneities in advanced materials. This effort has significant relevance to the Chemical Mechanical Planarization (CMP) process in the semiconductor manufacturing flow, where it is important to avoid defects in the final products. The Dunn group explores how nanoparticle size, size distribution and surface chemistry change with use conditions, and how these changes impact the removal rate and surface quality of the polished wafer.

Description: The light emitted by a single-photon emitter is fundamentally different from laser or thermally produced light. The key distinction relates to the time intervals between the emitted photons in the light beam. Photons can either cluster together in bunches or they can have regular gaps between them. In the latter case, an ion cannot emit two photons at once, which can lead to a non-classical light (single-photon emission) source. This is a required property for the development of future quantum optoelectronics and long-distance quantum communication applications using existing fiber-optical-based infrastructures. At SUNY Poly, Professor Spyros Gallis is leading research that aims to develop material platforms for quantum light sources at telecom wavelengths. In particular, the research is examining critical optical properties of erbium ions, enabled by a new class of SiC nanophotonic structures for telecom quantum-optical networks.
