Electron induced processes
WebPhotoinduced electron transfer ( PET) is an excited state electron transfer process by which an excited electron is transferred from donor to acceptor. [1] [2] Due to PET a charge separation is generated, i.e., redox reaction takes place in excited state (this phenomenon is not observed in Dexter electron transfer ).

WebApr 13, 2024 · Focused electron beam induced deposition (FEBID) is a versatile direct-write approach to produce nanostructures from organometallic precursor molecules. Ideally, the material is deposited only when precursors interact with and are dissociated by the impinging electrons so that the process is spatially defined by the electron beam. WebApr 19, 2024 · Hot-electron behavior determines the properties of optically-excited materials at very short timescales, between the femtosecond and the picosecond scale. Although ultrafast probing techniques are required for their study, their short lifetimes also open the possibility of using them in devices with short response times. 1 1.

Characterization of the Precision Laser ... Electron-beam processing or electron irradiation (EBI) is a process that involves using electrons, usually of high energy, to treat an object for a variety of purposes. This may take place under elevated temperatures and nitrogen atmosphere. Possible uses for electron irradiation include sterilization, alteration of gemstone colors, and cross-linking of polymers. Electron energies typically vary from the keV to MeV range, depending on the depth of penetratio…
WebAug 24, 2007 · Often this process occurs through thermal routes and the barrier is overcome through vibrational energy, but electronic transitions induced by photons or particles (typically electrons or ions) can lead to rapid desorption when the atom or molecule is excited to a higher-energy configuration that is repulsive in nature. WebWe report the energetic 8 MeV electron beam induced modification on linear and nonlinear optical process in Mn doped ZnO (MZO) thin films at different irradiation dosage. The modifications incorporated on third order nonlinear optical absorption were studied using Z-Scan technique in both continuous and pulsed laser regime.
