Helium irradiation effects in polycrystalline Si, silica, and single crystal Si [PDF]

open access: yes, 2012
Transmission electron microscopy (TEM) has been used to investigate the effects of room temperature 6 keV helium ion irradiation of a thin (≈55 nm thick) tri-layer consisting of polycrystalline Si, silica, and single-crystal Si.

Electron emission from electron-irradiated dielectrics

open access: yesIEEE Transactions on Electrical Insulation, 1991
Two methods for the measurement of the electron emission currents and the secondary electron yields for electron-irradiated dielectrics are discussed. Experimental results indicate that the dynamic measurement method for the secondary emission yield delta provides yield curves that are significantly lower than those obtained by conventional methods, at

Tuning the electronic band structure of PCBM by electron irradiation [PDF]

open access: yesNanoscale Research Letters, 2011
AbstractTuning the electronic band structures such as band-edge position and bandgap of organic semiconductors is crucial to maximize the performance of organic photovoltaic devices. We present a simple yet effective electron irradiation approach to tune the band structure of [6, 6]-phenyl-C61-butyric acid methyl ester (PCBM) that is the most widely ...

Electron-beam recording of surface structures on As-S-Se chalcogenide thin films

open access: yesФізика і хімія твердого тіла, 2020
The effect of electron beam irradiation on the amorphous chalcogenide film As38S36Se26 was studied. The formation of cones with a Gaussian profile on the surfaces of the films was found after local electron irradiation.

Effect of Electron-Beam Irradiation on Functional Compounds and Biological Activities in Peanut Shells

open access: yesMolecules, 2023
Peanut shells, rich in antioxidants, remain underutilized due to limited research. The present study investigated the changes in the functional compound content and skin aging-related enzyme inhibitory activities of peanut shells by electron-beam ...
