Influence of defects on the electrical and optical characteristics of blue light-emitting diodes based on III-V nitrides

Mártil de la Plaza, Ignacio ; Redondo, E. ; Ojeda, A. | American Institute of Physics | 1997-03-01

We have measured the electrical and optical properties of blue light-emitting diodes (LEDs) based on III-V nitrides. The current-voltage characteristic is described by means of the relation I = I-0 exp(alpha V). In this equation alpha is tempera[...]

Low interface trap density in rapid thermally annealed Al/SiNx : H/InP metal-insulator-semiconductor devices

Mártil de la Plaza, Ignacio ; González Díaz, Germán ; Redondo, E. ; Blanco, N. | Amer Inst Physics | 1999-02-15

A minimum interface trap density of 10(12) eV(-1) cm(-2) was obtained on SiNx:H/InP metalinsulator-semiconductor structures without InP surface passivation. The SiNx:H gate insulator was obtained by the electron cyclotron resonance plasma method[...]
