Triplet exciton dynamics in conjugated polymer films
… photo-oxidative degredation of polymer devices. Two-photon photoemission is used to probe triplet exciton relaxation dynamics in pristine conjugated polymer films and triplet-triple annihilation is determined to be an important deexcitation mechanism. Controlled photo-oxidation of conjugated …

Spectroscopic Measurements of Doping and Strain at Two-Dimensional Material Interfaces
… study uniaxial and biaxial strain in monolayer two-dimensional materials. Here I report SHG microscopy measurements of chemical vapor deposition (CVD) grown MoS2 on Si/SiO2 and c-cut sapphire, as well as in-plane WSe2/NbS2 in-plane heterostructures. I utilize a three-point polarization-resolved …
