Subatomic Features on the Silicon (111)-(7x7) Surface Observed by Atomic Force Microscopy.
The atomic force microscope images surfaces by sensing the forces between a sharp tip and a sample. If the tip-sample interaction is dominated by short-range forces due to the formation of covalent bonds, the image of an individual atom should reflect the angular symmetry of the interaction. Here, we report on a distinct substructure in the images of individual adatoms on silicon (111)-(7x7), t...
متن کاملImaging silicon by atomic force microscopy with crystallographically oriented tips
The images obtained by atomic force microscopy (AFM) originate from a convolution of atomic tip and sample states. Since the vertical resolution of AFM is approaching the picometer level, the atomic and subatomic structure of the tip is becoming increasingly important. Here, we demonstrate the preparation of crystallographically oriented AFM tips by breaking a silicon wafer along its preferenti...
متن کاملThe Effect of the Fractal Clusters on the Si (111)-7×7 Surface
one of the most important ingredients responsible for the success of integrated silicon technology is the Metal Oxide Semiconductor Field-Effect Transistor (MOSFET), and a major reason for its success is the MOSFET's scalability. Although the industry uses silicon and silicon dioxide in the electronic devices, it can be used for opto-electronic devices as well due to formation of fractal oxide ...
متن کاملModelling of ‘sub-atomic’ contrast resulting from back-bonding on Si(111)-7×7
It has recently been shown that 'sub-atomic' contrast can be observed during NC-AFM imaging of the Si(111)-7×7 substrate with a passivated tip, resulting in triangular shaped atoms [Sweetman et al. Nano Lett. 2014, 14, 2265]. The symmetry of the features, and the well-established nature of the dangling bond structure of the silicon adatom means that in this instance the contrast cannot arise fr...
متن کاملAdsorption and Thermal Decomposition of Acetaldehyde on Si(111)-7×7
The thermal stability of acetaldehyde on Si(111)7×7 was studied with HREELS, XPS, UPS, and TPD techniques. Acetaldehyde molecules were found to adsorb molecularly on the surface at 120 K, yielding HREELS peaks at 98, 124, 144, 185, and 380 and UPS peaks at 5.7, 7.6, 10.0, and 13.9 eV below Ef. Analysis of the XPS O1s (shoulder at 531; 532 eV) and C1s (288 and 285 eV) spectra indicated that the ...
