Building a 900-pixel imaging sensor using an atomically thin material

"molybdenum disulfide... on sapphire base via vapor deposition... laid on base of wire etched silicon dioxide, etching additional wiring on top... 30x30 grid, each pixel its own device capable detecting light and could be drained using electrode that made it ready for use again after something has been sensed... more efficient... each pixel used less than picojoule... responded slower to light so an all-purpose light sensor, but not fixture in camera... ideal sensing solution in a wide variety of IoT applications"
