Well-defined electrical properties of high-strain resonant interband tunneling structure
The GaAs/InAs high-strain resonant interband tunneling diodes (HSRITDs) have been implemented by metal organic chemical vapor deposition (MOCVD). The currentvoltage characteristics of variable quantum well and barrier thickness grown on (111) GaAs substrates are investigated. Experimental results reveal that the quantum barrier and well layer will influence currentvoltage properties such as the peak current density, valley current density, and peak-to-valley current ratio (PVCR). Both peak current and valley current density decrease with increasing layers width. This result also exhibits the variation of PVCR with layers width.
