Nano-sized earthquakes could boost phone cameras' performance
A team of Royal Melbourne Institute of Technology (RMIT) researchers believe they've found the secret to better phone cameras: teeny, tiny nano-earthquakes. To be exact, they've discovered that controlled sound waves can send ripples across 2D materials (flat surfaces that are a few atomic layers thick such as graphene), similar to ripples on the surface of water. These ripples can apparently change the electronic properties of a substance by carrying electrons across it. For their experiment, the team tested the technique on a photoluminescent 2D material, which emitted more and more light as the nano-earthquake intensified.
