An n-In0.53Ga0.47As/n-InP rectifier

Abstract
We report the current‐voltage (IV), capacitance‐voltage (CV), and photoresponse characteristics of n‐In0.53Ga0.47 As/n‐InP heterobarrier diodes. We find the conduction‐band barrier is Δεc = 0.22±0.02 eV. We find thermionic emission is the dominant mechanism for carrier transport across the heterobarrier. Also, to the level of sensitivity of our measurement techniques, no interface states have been detected.
