Surface electron accumulation and the charge neutrality level in In2O3.

Physical review letters, 2008
High-resolution x-ray photoemission spectroscopy, infrared reflectivity and Hall effect measurements, combined with surface space-charge calculations, are used to show that electron accumulation occurs at the surface of undoped single-crystalline In2O3.

Study on the ageing of insulators based on the surface charge accumulation process

The Journal of Engineering, 2018
In order to study the transient motion of the space charge around the air tower insulator and the charge distribution of the insulator, a two‐dimensional mixed numerical model of the insulator string based on chemical reaction is proposed. The simulation is used to obtain the space charge generation mechanism and its distribution on the insulator ...

Surface charge accumulation of particles containing radionuclides in open air [PDF]

Journal of Environmental Radioactivity, 2015
Radioactivity can induce charge accumulation on radioactive particles. However, electrostatic interactions caused by radioactivity are typically neglected in transport modeling of radioactive plumes because it is assumed that ionizing radiation leads to charge neutralization.
