WebSep 12, 2024 · When a metal surface is exposed to a monochromatic electromagnetic wave of sufficiently short wavelength (or equivalently, above a threshold frequency), the incident radiation is absorbed and the exposed surface emits electrons. This phenomenon is known as the photoelectric effect. Weboperation is observed with a very low single-photon impurity con-tribution of < 0.007. Here, is defined as the ratio of the laser background to the QD signal intensity. The single-photon purity is quantified in second-order photon correlation measurements (cf. data in Fig. 2D).
