New research puts a spin on environmental defects
Friday, December 20, 2019 En français Magnetic fields are all around us—and even in us—all the time, and they often prove useful in technologies we rely on, like hard drives, MRI scanners and the power plants that provide us electricity. Measuring small magnetic fields at an atomic scale would allow even more applications in […]

Zero-Dimensional Quantum Materials for the Next Generation of Highly-Selective Chemical Sensors
Summary Heavy metals are a major public health concern and their on-site detection in water supplies is not well served by existing lab techniques. We develop a new multi-modal platform comprising functionalized quantum dots of two-dimensional materials (2D-QDs) for the sensing of four highly-toxic heavy metal pollutants (arsenic, cadmium, lead and mercury). The zero-dimensional […]

Scanning Tunneling Microscopy of Quantum Materials, Devices and Molecules
Summary This project advances our ability to characterize and study novel quantum materials, quantum devices, and even individual molecules at the atomic level. By combining Non-Contact Atomic Force Microscopy (NC-AFM), Scanning Tunneling Microscopy (STM) and scanning gate methods, we correlate spatial information with transport properties and can locally manipulate charge, spin and structural states.
