Spectral tuning of InGaAs/GaAs quantum dot infrared photodetectors using selective-area intermixing
Quantum dot intermixing is a post-growth approach to tuning optoelectronic devices. SiO2 capping layers can enhance these effects through impurityfree vacancy disordering, whereas TiO2 caps can decrease intermixing. In this study, multi-colour quantum dot infrared photodetectors were fabricated through selective intermixing and four different encapsulants were investigated.
