Present address: Texas Instruments Tsukuba R&D Center Ltd., 17 Miyukigaoka, Tsukuba, Ibaraki 305-0841, Japan.;We have investigated the current transport behavior through single Si atom junctions on Si(111)-7×7 surfaces with a scanning tunneling microscope (STM). The atomic junctions betwee...
The Si(111)minus;7 times; 7/Eu interface investigated by means of electron spectroscopies 来自 ResearchGate 喜欢 0 阅读量: 18 作者: G. Rossi 摘要: We present a selection of data from the first spectroscopic investigation on the room temperature growth and annealing of the interface. A mixed ...
The behaviour of the ESR spectra when the magnetic field is rotated about the <100 > and <110 > directions shows that the centers have axial symmetry, the symmetry axis being along the <111 > directions. The results are interpretable in terms of an electron trapped at an oxygen vacancy ...
关于晶体取向的影响可大体归纳如下:在一定的氧化条件下,对于晶体取向分别为[111]、[110]和[100]三个方向的硅表面,其硅-二氧化硅结构中的固定表面电荷密度Q_{fc}之比约为3:2:1。这一结果可帮助分析固定表面电荷的起因。在上述三种取向中,(111)面的硅键密度最大,(100)面则最小,与上述顺序相同。由此推测固定电...
Fluorine etching on the Si(1 1 1)-7×7 surfaces using fluorinated fullerene molecules as a fluorine source has been investigated. At room temperature, adsorbed fluorinated fullerene molecules reacted with the Si(1 1 1)-7×7 surface to create a localized distribution of fluorine on the surface...
Scanning tunnelling microscopy has been used to study the interaction of elemental B with Si(111) 7×7 surface. Elemental B is evaporated at desired temperature (room temperature (RT), 800-1000°C), and the amount of B is varied with the evaporation time. The shapes and structures of the...
Kinetics of the (7 × 7) ↔ (1 × 1) Transition on Si(111) 来自 Wiley 喜欢 0 阅读量: 26 作者:W Telieps,E Bauer 摘要: The (7 × 7) (1 × 1) phase transition was investigated in situ by low energy electron reflection microscopy (LEERM). Heterogeneous nucleation of ...
The coercive force in the case of the polar configuration is ten times larger than that in the longitudinal configuration. This result shows that the preferred easy axis of magnetization for Ni/Si(111) lies on the surface plane. Since the in-plane component dominates the magnetic anisotropy, ...
7.2.4.2 Crystallography of (111) Si Reconstruction of (111) Si surfaces into (7 × 7) structures was first observed in LEED patterns (Ref. 9) similar to those shown in Fig. 8-33a. Disbelieved at first, these beautiful patterns were attributed to contaminated surfaces. It was some 25 yea...
