    Photocurrent-driven transient symmetry breaking in the Weyl semimetal TaAs

    Symmetry plays a central role in conventional and topological phases of matter, making the ability to optically drive symmetry changes a critical step in develo** future technologies that rely on such contro...

    Time-Resolved Raman Scattering and Transmission Measurements During Pulsed Laser Annealing

    Raman Scattering from a 7 nsec pulsed dye laser has been used to determine the onset of recrystallization following an 8 nsec dye laser excitation pulse in ion-implanted silicon. We find essentially complete r...

    A Novel Excimer Laser Crystallization Method of Poly-Si Thin Film by Grid Line Electron Beam Irradiation

    Excimer laser annealing technique is proposed to increase the grain size and controlling the microstructure of polycrystalline silicon (poly-Si) thin film. Our method is based on the lateral grain growth durin...

    Nondestructive Characterization of Solids Levels in High Viscosity Emulsions

    Emulsion explosives are extensively used in the construction and mining business. The physical consistency of emulsions can range from a stiff, putty-like substance to a fluid, pumpable product, depending on t...

    Pulsed Raman Measurements of Phonon Populations: Time Reversal, Correction Factors, and All That

    Transient optic phonon populations are measured in crystalline Si as a function of 532 nm laser energy density. The use of a continuously tunable pulsed dye laser as the Raman probe allows us to obtain, under ...

    Raman and Optical Properties of the Pulsed Laser Annealing Phase of Si

    Raman measurements of temperature reported earlier have been repeated using a doubled Nd: YAG pulse for excitation and an electronically delayed dye laser pulse. These results, together with a variety of exper...
