Inverse charge funnelling in a two-dimensional semiconductor paves the way to highly efficient solar cells The amount of energy received from the Sun by the surface of Earth in one hour, if converted into electricity, would power the whole world for one day. However, such energy conversion cannot be realised …
Graphene, a thin sheet of carbon atoms only one atom thick, has been used to realise a new photodetector (i.e. an electronic component used to sense and measure light) which is promising for some special applications. In the university of Exeter, me and my colleagues used a chemically-modified form of …
Photodetectors are electronic devices which are able to sense light. They are present in everyday tools such as mobile phones, televisions, remote controls, cars and much more. For example they are used to sense the amount of light which illuminates the screen of a mobile to tune its luminosity accordingly. …
