From Wikipedia, the free encyclopedia A scanning tunneling microscope (STM) is a powerful instrument for imaging surfaces at the atomic level. Its development in 1981 earned its inventors, Gerd Binnig and Heinrich Rohrer (at IBM Zürich), the Nobel Prize in Physics in 1986.[1][2] For an ...
High acquisition speeds with acceptable contrast and minimal photobleaching suddenly become essential, all without losing the instantaneous optical sectioning that a confocal microscope affords. Of particular interest here, disk-scanning confocal microscopes are proving to be a powerful tool in rapid imaging...
(Color online) Work principle sketch maps of scanning tunneling microscopy/spectroscopy.如果固定控制压电陶瓷形变的电压, 即维持针尖固定, 同时改变Vbias, 可以测量It随Vbias的变化关系. 此时, 样品的费米能(EF)相对于针尖会有eVbias的能量移动(如图1(右)所示, e为电子电量). 假设在测量能量范围内金属针尖的...
Based on the theory of mechanics of materials, a constant strain rate tensile test with in situ scanning electron microscopy (SEM) for measuring the adhesion of PVD films was developed, and the adhesion of a film to a substrate was determined in terms of the shear strain energy of the film...
