A scanning helium ion microscope (SHIM, HeIM or HIM) is an imaging technology based on a scanning helium ion beam. [2] Similar to other focused ion beam techniques, it allows to combine milling and cutting of samples with their observation at sub-nanometer resolution.
The scanning helium microscope (SHeM) is a form of microscopy that uses low-energy (5–100 meV) neutral helium atoms to image the surface of a sample without any damage to the sample caused by the imaging process. Since helium is inert and neutral, it can be used to study delicate and insulating surfaces.
As helium ions can be focused into a small probe size and provide a much smaller sample interaction than high energy (>1 kV) electrons in the SEM, the He ion microscope can generate equal or higher resolution images with good material contrast and a higher depth of focus. Commercial instruments are capable of sub 1 nm resolution. [21] [22]
Scanning helium microscope may refer to: Scanning helium microscopy; Scanning Helium Ion Microscope; Atomic nanoscope, which was proposed and discussed in the literature, but is not yet competitive with optical microscope, electron microscope, Scanning Helium Ion Microscope and various scanning probe microscopes
FEI Company (Field Electron and Ion Company) was an American company that designed, manufactured, and supported microscope technology. Headquartered in Hillsboro, Oregon , FEI had over 2,800 employees and sales and service operations in more than 50 countries around the world.
Field ion microscope image of the end of a sharp platinum needle. Each bright spot is a platinum atom. The field-ion microscope (FIM) was invented by Müller in 1951. [1] It is a type of microscope that can be used to image the arrangement of atoms at the surface of a sharp metal tip.
NanoSIMS (nanoscale secondary ion mass spectrometry) is an analytical instrument manufactured by CAMECA which operates on the principle of secondary ion mass spectrometry. [1] The NanoSIMS is used to acquire nanoscale resolution measurements [ 2 ] of the elemental and isotopic composition of a sample.
