Correlation between defect density and current leakage in InAs∕GaAs quantum dot-in-well structures

We present a study of InAs/GaAs quantum dot-in-well �DWELL� material using transmission electron microscopy and leakage current-voltage measurements. The spacer layers between the DWELL layers have a variety of annealing and growth temperatures. We show that there is a strong correlation between spa...
