The recent development of research in 2-dimensional (2D) semiconducting materials based on semiconducting transition metal dichalcogenides (TMDCs) enables a novel engineered quantum structures. Employing functional interface realized in high-quality van der Waals (vdW) heterostructures, gate-defined electronic systems can be fabricated. In particular, spatially confined quantum structures in TMDC can offer unique valley-spin features, holding the promises for novel mesoscopic systems, such as valley-spin qubits.
This seminar will introduce basic concepts and applications of Scattering Near-field Optical Microscopy (s-NSOM). In particular, the last generation microscope developed by Neaspec GmbH will be presented followed by a live demo in the afternoon at Harvard CNS Room G12.
Abstract: Solid state qubits have been studied extensively in quantum information science and technology for the last decade. Being a point defect in otherwise a perfect crystal, it gives rise to the localization of electrons and discrete energy levels. Compared to natural qubits such as atoms or ions, the solid system makes experiment much more convenient. However, the very same feature imposes inevitable challenges as well. Every qubit residing in the crystal sees slightly different environment due to local strain variation, nearby defects, etc.
CNS recently acquired new EDS/EBSD systems on our FEI Helios 660 dual beam FIB and an EDS system on our JEOL ARM STEM. We will be holding a workshop focused on EDS and EBSD on Thursday 11/19 from 9 - 5.
