Development of off-axis photoemission for 4-dimensional ultrafast electron microscopy
Ultrafast Electron Microscopy (UEM) is a novel technique for imaging which features generation of ultrashort electron probes to achieve on the order of femtosecond-nanometer spatiotemporal resolutions. In typical TEG based UEM architectures, photoemission is carried out from an on-axis LaB6 conical …

Nanoscale Coherent-Acoustic-Phonon Dynamics in Molybdenum Disulfide Using Ultrafast Electron Microscopy
… exceptional tunability of many properties (e.g., electronic band structure) via layer number and strain, and thus attracts interests in a broad range of device applications. Defects have been demonstrated to impact local properties and dynamics in a spatial range from a single atom to hundreds of …

Development of optical field emitter arrays
Optical field emitters are electron emission sources actuated by incident light. Optically actuated field emitters may produce ultrafast pulses of electrons when excited by ultrafast optical pulses, thus making them of interest for specific applications such as ultrafast electron microscopy, …
