    We are not convinced that the objections raised by Harman require basic me tallurgical changes , nor that further development is a waste of time and expen se. It is our belief that these grapes ought first to be tasted before they be declared sour. (AIP)

    We used synchrotron-radiation photoemission to investigate the chemical reactions that occur during the silver cladding process of BiSrCaCuO-used to increase the critical current density by over a factor of 50. We find that the Cu-O planes are not directly affected by the chemical reaction, and...

    An edge-emitting laser diode is described in which the epitaxial upper cladding layer is replaced with a metal contact selected for its optical as well as electrical properties. The structure is demonstrated with an In0.1Ga0.9N multiple-quantum-well laser diode operating at 412 nm with silver...

    Photonic crystal fibers guide light by trapping it in a periodic array of elements in the cladding area. We fabricated photonic crystal fibers by multiple extrusions of silver halide (AgClxBr1-x) crystals which are highly transparent in the middle infrared. The core of such a fiber consisted of...

    We investigate effects of Ni cladding layers on suppression of Ag agglomeration in Ag contacts on p-GaN using high-resolution x-ray diffraction. In the annealed Ag contact, Ag (100) grains disappear and agglomerate to form a selectively epitaxial growth of Ag (111). An ultrathin Ni contact layer...
