QS quantum dot sensor

Overview

Quantum Science’s core advantage is their INFIQ® QD technology.

INFIQ® technology is a ground-breaking quantum materials technology developed to address the decades-long-standing infrared sensing challenges.

Through innovative synthetic methods, INFIQ® technology produces highly light sensitive nanocrystals – called INFIQ® quantum dots (QDs). The materials can absorb much more light than conventional silicon-based materials and convert these absorbed photons into electrons, generating electrical signals efficiently for machine sensing applications. In particular, the materials can be finely tuned in by their chemistry to absorb broadband light from the visible to the infrared range.

The materials can be further treated to form QD inks that allow the creation of high-quality defect-free QD thin-film stacks, using low-cost single-step solution deposition methods, a perfect fit for wafer-scale processing.

Unlike conventional silicon and III-V technology, the INFIQ® QDs can also be deposited on flexible substrates for ultra-thin flexible electronics.

INFIQ® QDs have a technology-proven market-leading performance in QD devices and are in high demand from industry.
