from a scanning electron microscope was guided through the hole (Fig. 1). When the beam energy was around 20 keV, light with a wavelength of approximately 900 nm was produced. This output ...

When excited by an external stimulus (such as a laser pulse), a quantum dot can emit a single photon as the electron-hole pair recombines ... photonic structures for enhanced light-matter interaction, ...

In organic molecules, an exciton is a particle bound pair of an electron (negative charge) and its hole (positive charge ...
