Momentum-Resolved EELS of Two-Dimensional Quantum Materials
Studying low-energy collective excitations in low-dimensional quantum materials through momentum-resolved electron energy-loss spectroscopy.
Overview
My undergraduate research examined low-energy electronic excitations in two-dimensional quantum materials using momentum-resolved electron energy-loss spectroscopy. This work treated the spectrum as a joint function of momentum transfer and energy loss rather than as a single local spectrum.
Question
The central question was how collective excitation branches and their spectral signatures change with momentum. The project focused on extracting physically meaningful trends without presenting unpublished numerical results as established public claims.
Approach
The analysis combined spectral normalization, peak tracking, lineshape fitting, and dispersion extraction across momentum-resolved datasets. The work established the experimental and analytical foundation for my continuing interest in electron spectroscopy of quantum materials.
