The paper is studied on the performances of low power light-emitting diode and high power LED under high-current. After observing and measuring the degeneration of them, the Analysis of the failure mechanism is given. The degenerations of the optical parameter, electronic parameter and thermal parameter of high power LED under 600mA current stress are measured and the failure mechanism is analyzed. The I-V characteristic curve proves that the degeneration is happened in active region. Under high-current stress, the active region of high power LED is ageing which leads to much more defects. The degenerations of pins on the resin package, metal wire and surface layer metal pads are found with scanning electron microscope.

We study reliability of carbon nanofibers (CNFs) under high-current stress by examining CNF breakdown on four different configurations, suspended or supported, with/without tungsten deposition. The suspended results are consistently explained with a heat transport model taking into account Joule heating and heat dissipation along the CNF, while supported cases show a consistently larger current density just before breakdown, reflecting effective heat dissipation to the substrate.
