👉 In physics and chemistry, a "photoemissive" refers to an electron wave that is emitted from a material when it is excited by light. This process is also known as electron emission or photoionization. The photoemission occurs because of the interaction between electrons in the atomic structure of the material and photons, which are electromagnetic waves. In chemistry, photoemissive processes can occur in many different materials, including metals, semiconductors, and some organic compounds. These processes
