“…The electric field is highly concentrated at the sharp region rather than the flat region of materials according to the electromagnetism, even though the materials have nano-scale structures (figure 2) [23]. For instance, the electric field is highly concentrated at the tips of carbon nanotubes and metal nanostructures, resulting in a high emission current and bright emission patterns [21,[24][25][26][27][28][29].…”

Electric ﬁelds play a crucial role in modulating the electronic properties of nanoscale materials. Electron emission, induced by an electric ﬁeld, is a representative phenomenon. Experimental and theoretical aspects of such electron emission from graphene are brieﬂy reviewed. The emission occurs at the edge of graphene ﬂakes, not at the surface, because the edge highly concentrates the electric ﬁeld. Emission currents are sensitive to the edge shapes and edge ﬁctionalization. This review provides guiding principles for designing high-eﬃciency ﬁeld-emission devices by using graphene nanostructures.

“…For example, the Stark effect [16][17][18] promotes electron transfer and elicits spin-polarized conductivity, [19] and it can have drastic effects on the properties and reactivity. [20][21][22][23] In recent years, the molecular spectra and dynamics of many molecular clusters have demonstrated that EEF deforms and destroys cluster molecule from its ideal configuration, such as the borospherene B40 cluster [24] destruction under EEF (0.07 a.u.) and fullerene C 60 [25] under EEF (0.10 a.u.…”

On the basis of density functional theory (DFT), the geometry and infrared spectrum of the (AlP) 8 cluster have been calculated under external electric fields (EEFs). In addition, on the basis of time-dependent DFT, the ultravioletvisible absorption spectra, oscillator strengths, wavelengths, and hole-electron orbits of the first 20 excited states have been calculated. Under EEFs, the energy of (AlP) 8 gradually decreases, the dipole moment increases, and the molecular configuration significantly changes. In the infrared spectrum, the vibration frequency corresponding to the stretching vibration of the Al-P bond decreases, and a red shift occurs. With increasing EEF, the infrared spectrum splits and shows an obvious Stark effect; the ultraviolet absorption intensity is enhanced, and the molecular excitation energy decreases. Additionally, the excitation wavelength increases with increasing EEF. It is conclusively shown that the (AlP) 8 cluster is easily excited under an EEF. Separation of the holes and electrons of the (AlP) 8 cluster is obvious. Theoretical investigation of the spectra and excitation properties of (AlP) 8 is an important step toward a comprehensive understanding of the effects of EEFs on the molecular structure, stability, and dynamics.
