Controlling electronics with light: The magnetite breakthrough

 Physics General News
 21 June 2024
Researchers have discovered that by shining different wavelengths (colors) of light on a material called magnetite, they can change its state, e.g. making it more or less conducive to electricity. The discovery could lead to new ways of designing new materials for electronics such as memory storage,...
