CNM's QuEEN-M Platform Combines Atomic-Resolution STEM with Ultrafast Time-Resolved Capabilities
By
Rusty Flint
A respectable bake. You'd come back tomorrow for another.
Summary
The Quantum Emitter Electron Nanomaterial Microscope (QuEEN-M), a new platform available through the Center for Nanoscale Materials (CNM) user program, integrates atomic-resolution scanning transmission electron microscopy (STEM) with cathodoluminescence spectroscopy and ultrafast electron pulsing. This combination enables time-resolved studies of materials' dynamic processes at sub-nanometer spatial resolution and picosecond timescales—a capability previously difficult to achieve. A key design feature is the Attolight CL system's fiber-coupled parabolic mirror, decoupled from the microscope's objective lens.
