"Colloidal quantum dots (CQDs) have recently gained attention as materials for manufacturing optoelectronic devices in view of their tunable light absorption and emission properties and compatibility with low-temperature thin-film manufacture. The realization of CQD inkjet-printed infrared photodetectors has thus far been hindered by incompatibility between the chemical processes that produce state-of-the-art CQD solution-exchanged inks and the requirements of ink formulations for inkjet materials processing.
We fabricate inkjet-printed photodetectors exhibiting the highest specific detectivities reported to date (above 1012 Jones across the IR) in an inkjet-printed quantum dot film. As a patternable CMOS-compatible process, the work offers routes to integrated sensing devices and systems."
Previous Invisage CTO, right? Previous material must be something like PbSe, this guy is good at solar-cell.
ReplyDeleteWasn't that quantum dot technology by InVisage a monumental failure? Also I thought Apple bought it, regretted it, and shut down the entire company.
ReplyDeleteInteresting how much envy there is in this imaging community. It's a bit sad.
ReplyDeleteLooking at such a story from outside, I would argue that if you sell your company to Apple, you must have done at least something right...
