Quantum Science achieves leading device performance for lead-free SWIR
The UK-based nanomaterials innovator has launched a quantum dot technology that is lead-free, to push the boundaries of what sustainable nanotechnology can accomplish.
Demonstrating the company’s commitment to making advanced material technology accessible, effective and versatile, Infiq LF-QDs are tuned out to the short-wavelength infrared (SWIR), an ideal spectral region of interest for applications such as telecommunications, light detection and ranging (lidar), surveillance and safety. Such long wavelengths from this class of material represent the state of the art in the field and places QS as the technology leader.
Further showcasing the potential of Quantum Science’s development, SWIR devices fitted with Infiq LF-QD have demonstrated external quantum efficiency (EQE) in excess of 20 % at low bias conditions. Higher EQE is found to be possible with a higher operating bias, which creates significant potential for market leading performance and underlines Infiq LF-QD as the new benchmark in quantum dot technology.
Dr Hao Pang, CEO and founder of Quantum Science, said: “With the market launch of Infiq LF-QD, we are welcoming a new dawn in what nanotechnology can achieve and importantly, we are accomplishing this without the use of lead.”
“Demand from the industry is climbing, which makes our lead-free technology all the more vital. We are connecting with diverse customers, including image sensor fabricators, design houses, camera module makers, semiconductor material suppliers and process technology specialists to name just a few examples of where the technology is making waves.”
“We pride ourselves on leading the market, but that alone isn’t enough – we are also making it scalable and accessible. With Infiq LF-QD, we are targeting real market disruption and technology that makes a true difference to the world around us.”
Dr Pang added: “The development and launch of our lead-free quantum dot technology is just a small indicator of where we’re taking the business in the long-term. Nanotechnology is central to the success of the technology sector in all its guises, which means what we do today has an impact on tomorrow. By adding sustainability to the mix and letting it enhance, rather than hinder, material performance for SWIR devices, we are creating something very special.”
