Doping effect on carrier occupation and transport in InAs/GaAs quantum dot infrared photodetectors: A capacitance-voltage spectroscopy study


Journal Article

Impurity centers induced by dopants in InAs/GaAs quantum-dot systems affect energy level occupation and carrier transport in multi-layer QDIPs. In order to better understand doping effects and to optimize device performance, capacitance-voltage spectra are investigated. © 2007 Optical Society of America.
