One of the pioneering achievements in condensed matter physics of the 20th century is the observation of the quantum Hall e↵ect (QHE) in which the Hall resistance in a two-dimensional (2D) sample takes on quantized values in the presence of a strong perpendicular magnetic field. The precise quantization of the hall resistance to one part in a billion has provided a practical, worldwide resistance standard. A long-standing goal has been to realize a similar state of matter but without the need of a strong quantizing magnetic field. The quantum anomalous Hall e↵ect (QAHE) is such a state that is predicted …

Low-dimensional nanostructures exhibit distinct properties from their bulk counterparts. Here the synthesis of novel low-dimensional nanostructures is demonstrated using both top down and bottom up processes and their properties are investigated. Two-dimensional (2D) binary sesquichalcogenides are introduced as a viable material platform for phase change random access memory, photodetection, and the investigation of topological insulator surface states. An exponential relationship is observed between layer thickness and energy consumption during switching of 2D phase change devices, ultra-high responsivity in 2D photoresistors, and surface-rich conduction in 2D topological insulator nanoplates. Additionally, methods for the assessment of chemical purity, stoichiometry, and dimensions of …
