Effect of Proton Irradiation Upon Hydrogen Reduction of NiO

Abstract

It is shown that the reduction of a metal oxide such as nickel oxide by hydrogen gas is strongly influenced by nuclear irradiation. The initial induction period is shortened and the subsequent reduction accelerated. The effects anneal out at higher temperatures. A probable mechanism of this acceleration is suggested.

Proton Radiation Hardness of Perovskite Tandem Photovoltaics

“…20 Proton, gand UV-irradiation is known to induce defects in NiO that increase its conductivity while also leading to conversion from p-type to n-type behavior. [49][50][51] This deteriorates the energetic alignment between PTAA and ALD NiO, leading to less efficient extraction of charge carriers, thereby affecting FF and maximum power point (MPP) of the perovskite top cell. The luminescence of perovskite absorbers sandwiched between two selective contacts is known to be heavily influenced by surface recombination and charge carrier extraction into the selective contacts.…”

The Solid State

“…One class of these is the so-called "hot-atom" reaction, and Harbottle & Sutin (134) have proposed a model for the chem ical effects of nuclear recoil in solids. (138) to influence strongly the hydrogen reduction of NiO. These hot spots merge to give a rela tively uniform zone of high temperature, which has a lifetime of ",10-11 sec., during which chemical reactions involving the recoil atom may occur.…”
