Niobium dioxide (NbO2) is a highly correlated material that, like vanadium dioxide (VO2), exhibits a first-order insulator-to-metal transition (IMT) at a material-dependent critical temperature, accompanied by a structural transformation from monoclinic to rutile. The nature of the IMT in VO2 has been discussed at length, while fewer studies have been carried out on NbO2. Here, we present ultrafast pump-probe studies comparing reflection measurements to the first ultrafast transient transmission measurements of this optically-induced transition in NbO2 thin films, as well as compare these studies to similar ones carried out on VO2 thin films.
