We report on the observation of photoconductivity in elemental gallium confined at an interface with glass. The effect is associated with a fully reversible light-induced structural transformation in the metal, which affects a surface layer only a few nanometers thick. The effect has the potential for applications in optically fast, broadband photodetectors.

    We report that a nanoscale laser-induced structural phase transition involving just a few nanometers of gallium at an interface with silica can drive reversible changes in the optical properties of the interface in a very broad spectral range from 440 to 680 nm and beyond. At temperatures up to...

    The effects of a graded composition layer at the amorphous silicon/nitride interface are studied using transient photoconductivity. The graded layer causes a large increase in the density of slow states (electrons trapped within the nitride), but does not influence the fast interface states. The...

    The photoconductance decay (PCD) measurement is a fast and simple method to characterize amorphous/crystalline (a-Si:H/c-Si) silicon interfaces for high-efficiency solar cells. However, PCD only yields information concerning the overall recombination rate in the structure. To overcome this...
