Dynamics in semiconductor materials will be studied using optical pump-probe methods. Rapid changes in optical properties of materials are measured using supercontinuum spectral interferometry and other techniques. Coherent control techniques for all-optical injection of charge and spin currents, coupled with spatially-resolved pump-probe measurements, will be used to study carrier transport. Changes in linear and nonlinear optical susceptibilities in an applied DC or THz electric field are also of interest, including the Franz-Keldysh effect. Materials of interest include layered semiconductors and novel 2D materials. Research is done in close collaboration with other groups at NIST with expertise in complementary techniques and materials growth.
