Research Interests
Research in Professor Long Ju’s lab focuses on understanding light-matter interactions and electron transport in novel quantum materials. Of particular interest are atomically thin materials and van der Waals hetero-structures of them. These materials host a variety of fascinating electronic and optical properties individually, and they offer exciting opportunities to explore possibilities enabled by controlling the stacking order and electrically tuning the band structure and charge doping. Especially, such materials provide a new platform to design and engineer more exotic quantum phenomena when electron correlations and topology are included. We develop problem-oriented experiments by employing various optical spectroscopy and microscopy tools in a broad spectrum range from UV to THz, as well as DC transport measurements. Ultrafast optical techniques and scanning probe optical microscopy will be utilized to study dynamical properties on a time scale down to femtoseconds and a spatial resolution of nanometers. Most importantly, device fabrication and application of electric and magnetic fields will be combined to achieve external control of material properties.
