Stylus Techniquesmpetus because of the need for accurate methods of quality control during the war, in particular, because of the need for controlling the quality of surfaces of components manufactured by subcontractors. Since then, the uses of stylus techniques have increased manyfold. Reduction of the dimensionalGlucose 发表于 2025-3-30 22:13:56
Electron Microscopyracks nucleate at the surfaces of materials and the rate at which they nucleate is greatly influenced by the detailed topography of the surfaces. in the field of thin-film devices, the manufacturing tendency has been to reduce the size of electronic components. Surface-to- volume ratios are now exceCESS 发表于 2025-3-31 01:07:34
Scanning Electron Microscopycludes all information relating to topographical features, morphology, habit and distribution, identification of differences based on chemistry, crystal structure, physical properties, and subsurface features, among others.CHOP 发表于 2025-3-31 08:49:15
Field Ion Microscopye capable of giving an image of the atoms themselves. It was developed from the earlier field emission microscope and has recently been given another dimension by the addition of a time-of-flight mass spectrometer. This latter combination has been described as the atom probe and it is well-named sin蚀刻 发表于 2025-3-31 09:47:58

Electrochemical Techniquesns and tell something about the state of the surface. Electrochemical measurements, however, require an electrolyte on one side of the interface, and high potential gradients across this region may occur (≈ 10. V/cm). the surface can be materially different from that in equilibrium at the solid-gas
