Abstract
:
GaAs/AlAs double barrier resonant tunneling diodes have been studied by I-V-T measurements over the temperature range 77K-350K. No resonant tunneling peaks or Negative Differential Resistance regions (NDR) was observed. This has been attributed to poor material's quality which has a high degree of defects. These tend to destroy coherent tunneling and reduce peak to valley ratio. The I-V-T characteristics have been analyzed on the basis of forward currents in a Schottky diode. It is found that the Richardson's plots follow a modified relationship indicator of a Thermionic-Field-Emission (T.F.E.) from the emitter into the barrier. The ideality factor (n) dependence on temperature has been studied in the basis of T_0 effect. I-V-T data analyzed of the basis of a Gaussian distribution indicates then the mean barrier height varies between 0.28eV to 0.34eV
