This video is about Scanning Tunneling Microscopy (STM) and Atomic Force Microscopy (AFM), which gives excellent resolution and magnification.

Assignment 4: Make comparison between traditional optical, electron microscopies and scanning probe microscopy (STM and AFM) (34pts) Optical Microscope

볼 수있는 또 다른 차이점은 AFM의 팁이 표면에 부드럽게 닿는 반면 STM에서는 팁이 표면으로부터 짧은 거리에 유지된다는 점입니다. This third generation of the LT STM enables our customers to carry out the most advanced low temperature STM, spectroscopy and QPlus® AFM experiments. And like its previous iterations, the ease-of-use, stability and proven reliability in the LT STM ensure a high productivity, workhorse microscope. AFM vs STM AFM odnosi się do mikroskopu sił atomowych, a STM oznacza skaningowy mikroskop tunelowy.

Atomic force microscopy (AFM) is a powerful imaging technique that, by scanning a sharp tip (typical end diameter 5–10 nm) over a surface, can produce topographical images which quantify surface morphology on an area scale comparable to that encountered by a colloid interacting with that surface (Binnig et al., 1986). STM is generally applicable only to conducting samples while AFM is applied to both conductors and insulators. In terms of versatility, needless to say, the AFM wins. Furthermore, the AFM offers the advantage that the writing voltage and tip-to-substrate spacing can be controlled independently, whereas with STM the two parameters are integrally linked. These methods include Atomic Force Microscopy (AFM), Scanning Electron Microscopy (SEM), and Transmission Electron Microscopy (TEM). In conclusion, the most appropriate technique depends on the sample type and the desired information to be measured. Researchers usually choose techniques based on the availability and familiarity of each method.

The microscope has two modes, a scanning tunneling microscope (STM)-SQUID mode for conductive materials and an atomic force microscope (AFM)-SQUID mode even for insulating ones. The submicron magnetic domains of ferromagnetic thin films, fine magnetic patterns of magnetic hard disk and magneto-optical disk, and so on were clearly observed.
