A new theoretical approach is proposed to explain the nature of the well-known narrow and intense optical J-band of ...

Two-photon emission (2PE) is a process in which an electron transition between quantum levels occurs through the simultaneous emission of two photons. Two-photon emission is interesting because it ...

Electron moved to “better navigate delays in clean energy policy implementation and capitalize on clarity as it emerged.” ...

to \(E_{1}\) the energy of the photon can be worked out using the following: As the energy levels have different values, each of the possible electron transitions within an atom will produce a ...

Abstract: In situ transmission electron microscopy allows us to study growth processes and phase transitions which are important in semiconductor processing. It provides a unique view of dynamic ...

This work utilizes electron energy loss spectroscopy (EELS) to identify oxidation state of alloying elements in Ni-based alloys after exposure to molten chloride salt systems. Pure Ni and Ni-20Cr ...

This creates vacancies, leading to a cascade of electron transitions within the atom as electrons from higher energy levels drop down to fill the vacancy. The energy released during these transitions ...
