(Nanowerk News) Researchers at Nagoya University in Japan have developed gallium-doped zinc oxide (GZO) nanosheets that may enhance camera resolution in compact devices, including smartphones and medical endoscopes. These nanosheets enable a single pixel to detect the intensity of red, green, and blue (RGB) light while remaining nearly transparent, unlike conventional sensors. They are ultrathin, lightweight, and can withstand temperatures up to 400 degrees Celsius, making them suitable for extreme environments such as space hardware and automotive systems.
