By a recent decretal an indulgence had been promised by the pope to all who should ascend upon their knees "Pilate's staircase," said to have been descended by our Saviour on leaving the Roman judgment hall and to have been miraculously conveyed from Jerusalem to Rome.

由于新近颁布的御旨,教皇应许凡是双膝下跪攀登"彼拉多台阶"的人,他们的罪都可以赦免;据说,这个台阶就是从前救主离开罗马巡抚审判厅的时候所走过的台阶,后来是以神奇的方式从耶路撒冷运到罗马来的。

One is at low growth temperature, the origin of mound formation can be attributed to an intrinsic growth instability of a singular surface in the presence of so-called Ehrlich-Schwoebel step-edge barrier, which inhibit the downward movement of adatoms at surface step-edges. The other is at high temperature, or at low Ⅴ/Ⅲ ratio, the reason of mound formation is related to phosphorus deficiency.

其主要原因有两种,第一种是生长温度较低时,由于吸附原子受到附加的ES台阶边垒的阻碍作用,使扩散运动不能向台阶下面运动,而在台阶上面形成小丘,第二种是生长温度较高或Ⅴ/Ⅲ较低时,因生长中缺磷造成In的堆积而产生。

We found that during the growth process the double steps first grow separately and the connected by short bridge before tangential growth. After eighth or ninth layer the spiral steps would merge into intact elliptic layers. At the merging point right-handed spiral sources might appear but the left ones always overgrow it which made the whole growth topography looked like left-handed apparently. It indicated that the EAFP molecules has strong ability to adjust itself to adapt the environment. 5. Through various analysis of interactions in the EAFP crystals it indicated that there were 218 residue interactions between 12 symmetry-related EAFP molecules around one EAFP molecule, 18 strong ones and 72 weak ones .

EAFP在低过饱和度下的螺旋生长过程中会出现台阶的合并,从而表现出单-双的螺旋台阶,在小范围扫描中捕获到了这种现象,使得对螺旋生长台阶的合并过程有了更加深入的认识;并且台阶的生长受到沿晶体学b轴方向上的21螺旋对称的控制;当台阶生长至第八到第九层时,螺旋台阶会自动地形成完整的生长层,这充分说明了EAFP分子或分子簇具有良好的自身调节能力,这样在晶体生长过程中,晶体的缺陷减少,晶体质量提高,这也可说明EAFP晶体的x射线衍射能力很强的原因。

This project was established based on the first cooperative development of optical in situ real time detecting technique probing the atomic scale layer-by-layer epitaxy growth of oxide film. Over the last three years, we have given full play to the advantages and characteristics of both sides and have finished the assumptions and plans of this subject satisfactorily. 1. In Institute of Physics, we set up advanced oblique-incidence reflectivity difference equipment and wrote one data acquisition procedure that made the simultaneous detection of optical signal and RHEED signal into reality. 2. The first observation of sustained oscillations over hundreds of monolayers in both real and imaginary signals during the epitaxy growth of SrNb0.1Ti0.9O3 on SrTiO3 substrate in LMBE testifies that oblique-incidence is an excellent method to detect and monitor film epitaxy growth real time. 3. For the first time, we verify that oblique-incidence reflectivity difference method can be used to monitor the layer-by-layer growth mode during continuous growth through the correspondence between optical signals to atomic or molecular step edge density on the growth surface. 4. Phenomenological analysis shows that optical signals comprise three parts, the first is proportional to the average thickness of the film and depends on the bulk phase dielectric response; the second is proportional to the coverage of terraces and depends on the dielectric response of atoms or unit cells in the terrace; the third is proportional to the coverage of step edges and depends on the effective dielectric response of atoms or unit cells at step edges. This makes oblique-incident reflectivity difference technique a quantitative macroscopic method to monitor film growth.
