A new research paper published in the journal Nature Physics has revealed an intriguing competition mechanism in vacuum ultraviolet light. The discovery could have implications for a range of applications, from solar energy harvesting to ultrafast electronics.

The research team, led by scientists from the University of Tokyo, studied light emission from diamond-like carbon (DLC) films exposed to vacuum ultraviolet (VUV) light. The team found that, when exposed to low levels of VUV light, the DLC films emitted both light and electrons. However, when the VUV light intensity was increased, the electrons decreased and the light intensity increased. This competition between the light and electrons is what the researchers call a “VUV competition mechanism.” The team believes this discovery could have implications for a range of applications. For example, it could be used to control the efficiency of solar energy harvesting and ultrafast electronics.
