To advance research in nanoscale science, engineering and technology, the National Science Foundation (NSF) will provide a total of $81 million over five years to support 16 sites and a coordinating office as part of a new National Nanotechnology Coordinated Infrastructure (NNCI).
The tool of the month for September is the Atom Probe Tomography (APT) system. Users at the CNS have access to the Cameca LEAP 4000X HR. This tool provides researchers provides nano-scale surface, bulk and interfacial materials analysis of simple and complex structures with single atomic identification and accurate spatial positioning. The system works by systematically evaporating a needle-shaped prepared sample, either by directly ionization using a focused UV laser or a strong electric field applied to the sample. The evaporated ions travel to a… Read more about September Tool of the Month: Cameca 3D Atom Probe
Abstract: The 5-year renewal plans for the STC for Integrated Quantum Materials will be presented. Our vision is to use quantum materials to enable quantum sensors, quantum communication, and quantum computing. Center faculty at Harvard, Howard University, and MIT will pursue four Research Areas: Van der Waals Heterostructures, led by Philip Kim (Harvard), Discovery of New Topological Crystals, led by Joe Checkelsky (MIT), Topologically Protected Qubits, led by Amir Yacoby (Harvard) and Pablo Jarillo-Herrero (MIT), and Quantum… Read more about CNS Seminar, "Science and Technology Center for Integrated Quantum Materials," Professor Robert M.

Abstract: Decoherence due to local noise is the worst enemy of quantum information. To combat this, topological quantum computing has been proposed as a powerful and elegant scheme to encode quantum information globally, and hence stay robust against local perturbations. In the past five years, this field has begun to see experimental breakthroughs made possible by combining superconductivity and various low-dimensional quantum materials with significant spin-orbit interaction. Here in the Yacoby group, we fabricate superconducting devices… Read more about CNS Seminar: "Probing Topological Superconductivity in HgTe/HgCdTe Quantum Wells," Hechen Ren, Yacoby Group, HU
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. In this presentation, we… Read more about CNS Seminar, "Engineering Quantum Confinement in Semiconducting van der Waals Heterostructure," Professor Philip Kim
