Tunnel junctions could have a great impact on gallium nitride and aluminum nitride-based devices such as light-emitting diodes and lasers by overcoming critical challenges related to hole injection and p-contacts. This paper demonstrates the use of GdN nanoislands to enhance interband tunneling and hole injection into GaN p-n junctions by several orders of magnitude, resulting in low tunnel jun...

Abstract When liquid aluminum is exposed to air, an oxide layer instantaneously forms on the surface of melt, which, when enfolded, becomes a double film defect (bifilm), producing entrained air pockets forming voids, cracks, and areas stress. Studies reactions between trapped inside bifilms surrounding melt have produced reaction products such as AlN. In this study, examination fracture surfac...
