Research of Influencing Factors on Material Quality for an Electrically Tunned Diode with Constant γ |
| |
| Abstract: | This paper describes recent progress of GaAs epitaxial material for an electrically tunned diode with constant γ. The influence of GaAs substrate quality on both the surface morphology of epilayers and the interfaces between epilayers and sub-states is analyzed. The dependence of doping profile of epilayers on the epitaxial growing process is studied. Then the influence of the epilayer carrier concentration profile on the C-V properties of the electrically tunned diodes with constant γ is discussed. Finally, the results of diodes made by the materials are also given. |
