Depletion region surface effects in electron beam induced current measurements. [PDF]
J Appl Phys, 2016 Electron beam induced current (EBIC) is a powerful characterization technique which offers the high spatial resolution needed to study polycrystalline solar cells. Current models of EBIC assume that excitations in the p-n junction depletion region result in perfect charge collection efficiency.

Investigation of Bulk Traps by Conductance Method in the Deep Depletion Region of the Al2O3/GaN MOS Device. [PDF]
Nanoscale Res Lett, 2017 Conductance method was employed to study the physics of traps (e.g., interface and bulk traps) in the Al2O3/GaN MOS devices. By featuring only one single peak in the parallel conductance (Gp/ω) characteristics in the deep depletion region, one single ...

Ion concentration polarization-based continuous separation device using electrical repulsion in the depletion region. [PDF]
Sci Rep, 2013 We proposed a novel separation method, which is the first report using ion concentration polarization (ICP) to separate particles continuously. We analyzed the electrical forces that cause the repulsion of particles in the depletion region formed by ICP.

Nano-grain depletion in photon-dominated regions
Astronomy & Astrophysics, 2022 Context. Carbonaceous nano-grains play a fundamental role in the physico-chemistry of the interstellar medium (ISM) and especially of photon-dominated regions (PDRs). Their properties vary with the local physical conditions and affect the local chemistry and dynamics. Aims.
