Since the early 2000s, the impending end of Moore's scaling, as the physical limits to
shrinking transistors have been approached, has fueled interest in improving the …

Carrier dynamics is crucial in semiconductors, and it determines their conductivity, response
time, and overall functionality. In flat bands (FBs), carriers with high effective masses are …

Semiconductor heterojunctions have gained significant attention for efficient optoelectronic
devices owing to their unique interfaces and synergistic effects. Interaction between charge …

Scanning electron microscopy (SEM), a century-old technique, is today a ubiquitous method
of imaging the surface of nanostructures. However, most SEM detectors simply count the …

We present an efficient method to produce laser-triggered proton pulses well below 500 ps
pulse width at keV energies. We use femtosecond photoelectron pulses emitted from a …
