Microelectronic devices based on silicon and complementary metal-oxide semiconductors, or CMOS for short, have enabled substantial breakthroughs in computer, telephone, and camera technology during the last 40 years, particularly in the field of image processing.
Microelectronic devices based on silicon and complementary metal-oxide semiconductors, or CMOS for short, have enabled substantial breakthroughs in computer, telephone, and camera technology during the last 40 years, particularly in the field of image processing. Because it is difficult to combine CMOS with semiconductors other than silicon, microelectronic devices were limited to microelectric circuits and cameras that detected visible light.

It was recently discovered that this difficulty might be solved by a group of scientists from the Institute of Photonic Sciences in Spain. Dr. Stijin Goossens and colleagues combined graphene with CMOS technology to build a high-resolution photo sensor with a wide dynamic range. The outcomes of the study were published in the journal Nature Photonics.
This is the first sensor of its kind to be able to detect not only visible light but also ultraviolet and infrared radiation, making it unique in the world. According to the experts, at room temperature, the manufacturing process may be completed rapidly and inexpensively.
The sensor can also be utilized in conjunction with flexible surfaces, which is another advantage. There are a range of uses for graphene-CMOS technology that could be used in the future. In addition to smartphones, this technology may be used in a variety of applications including fire control systems, medical imaging systems and automobile sensors.
