Ion beam irradiation and doping effect on 1D and 2D materials


Ion beam irradiation and doping effect on 1D and 2D materials

Ou, X.

In this lecture, I will give a brief review on the doping of the nanostructure by ion beam implantation and irradiation. Because of the high surface to volume ratio of the low-dimensional materials, the doping behavior is quite different from the bulk materials. Some examples on doping of nanowire1,2 and graphene by ion beam will be discussed. Meanwhile, ion beam irradiation can create the oxygen vacancy in functional oxide in a controllable way. The generation of oxygen vacancies acting as "dopants" modifies the properties of the oxide. An example of tuning the resistive switching characteristics of resistive switching oxide 3 by low energy ion irradiation will be discussed.4

Keywords: doping of the nanostructure; ion beam implantation and irradiation
