Quantum dot (QD)-based probes for multiplexed determination of heavy metal ions
Microchimica Acta, 2020 Heavy metal contamination is a major global concern and additive toxicity resulting from the exposure to multiple heavy metal ions is more pronounced than that induced by a single metal species.

High Temperature Operation of Co-Doped InAs Quantum Dot Laser for O-Band Emission
IEEE Photonics JournalWe demonstrate high temperature operation of InAs quantum dot lasers through active region engineering. We grew an n-doped region within the InAs quantum dot (QD) layer and incorporated a 10 nm p-GaAs modulation-doped layer within a 43 nm GaAs spacer ...
