Most interesting, worked on a project that needed to get low light images for input to modeling.
2D Material May Enable Ultra-Sharp Cellphone Photos in Low Light
Pennsylvania State University News, Jamie Oberdick, December 9, 2022
Researchers at Pennsylvania State University (Penn State) have developed a pixel sensor using a novel two-dimensional material that could allow mobile phones to take ultra-sharp phones with low-energy in-sensor image processing. The sensor uses a molybdenum disulfide semiconductor featuring strong signal conversion, charge-to-voltage conversion, and data transmission capabilities. The researchers arranged the sensors into a nine-square-millimeter array comprised of 900 pixels, each of which take up around 100 micrometers. Penn State's Darsith Jayachandran said, "They are much more sensitive to light than current CMOS sensors, so they do not require any additional circuitry or energy use. So, each pixel requires much less energy to operate, and this would mean a better cellphone camera that uses a lot less battery." ... '
