SUMMARY
Indium Phosphide (InP) diodes exhibit a larger peak-to-valley current ratio compared to Gallium Arsenide (GaAs) diodes due to the unique electronic band structure and valley coupling in InP. The discussion highlights that the coupling between valleys in InP allows for enhanced electron mobility and reduced scattering, leading to improved performance in high-frequency applications. In contrast, GaAs diodes, while effective, do not achieve the same level of efficiency in this regard.
