Channeling implantation

WebIon channeling is another effect that may add uncertainty in the depth. This effect leads to an underestimation of the implantation depth for ions implanted into any crystalline … Webstage holding the sample during implantation was kept at room temperature and no post implantation heating was carried out. Because of the high thermal conductivity of tungsten (164 W/(m-K) and the implant duration, it is not expected that the sample temperature increased significantly above room temperature during the implantation.
