Effect of electron-irradiation on layered quantum materials

Technological advancement towards the quantum era requires secure communication, computation and ultra-sensitive sensing capabilities. Layered materials (LQMs) have remarkable optoelectronic properties that can usher us into era. Electron microscopy is tool of choice for measuring these LQMs at an atomic nanometre scale. On other hand, electron-irradiation modify various material properties, including creation structural defects. We review different types defects, as well electron elastic- inelastic-scattering induced processes. Controlled modification using electron-irradiation, single-photon emitters discussed. Protection damage via encapsulation by layered encouraged. finally give insights challenges opportunities, creating novel structures beam.
