Laser-induced breakdown spectroscopy (LIBS) is a method of material analysis used to determine the composition of a sample by ablating it with an ultrafast laser pulse. By monitoring the light emission from the resulting plasma, the elemental composition of the sample and the concentration of...

As communications technologies continue to grow, the role of gallium nitride (GaN) transistors for high-frequency applications continues to grow as the speed requirements of more and more applications exceed the abilities of silicon. Today the vast majority of commercial GaN devices use HEMT...

Advancements in scanning tunneling microscopy (STM) have enabled atomic-scale lithographic patterning of logic gates, memory, and wires, by selectively passivating hydrogen (H) atoms on a H-terminated silicon (Si) surface. However, atomically fabricated systems encounter challenges of developing...

Marin Calzada, Jesus Alejandro
Scanning probe microscopes routinely provide atomic resolution of numerous materials, but lack the tools to investigate their ultrafast dynamics. Laser pulses can be generated in the femtosecond or even attosecond regime, but their spatial application is restricted by the diffraction limit....

Ultrafast terahertz (THz) spectroscopy is presently the most powerful tool available to materials scientists for directly probing ultrafast conductivity dynamics. Its low center frequency and phase-resolved measurement, which yields sub-picosecond temporal resolution, make it ideally suited for...
