By low temperature (145K) deposition method, we prepared such flat Pb films on the Si (111) substrate over a wide thickness range (from 10ML to 32ML). The unique growth behaviors were investigated by RHEED, STM and ARPES. A critical thickness of 10ML is established, at which the atomically flat Pb films become stable at room temperature. Between 10ML and 20ML, the growth exhibits a quasi bi-layer growth mode. Above 21ML, a layer-by-layer growth mode was observed.

The results show that the growth rate of tetrapod ZnO is controlled by spiral growth and its crystallization is via VLS model. The condensation of tiny zinc droplets in zinc vapor is the key factor of the formation of tetrapod ZnO. The growth steps are formed on the terminated faces as zinc diffuses outwards and the elongation of whiskers continues until zinc inside the droplets is depleted. VS crystallization, which has little effect on the elongation growth, takes place on side faces of the whiskers and consequently makes the whiskers radius increase.
结果表明: T-ZnO晶须的结晶作用是气-液-固方式,晶须生长受螺旋生长机理控制;锌蒸气中产生凝聚生长的锌液滴是制备T-ZnO晶须的关键,锌从液滴内向外扩散在晶须的端面产生生长台阶,随着液滴内的原子向外不断扩散,针体部分就不断地伸长生长,当液滴内的原子全部消耗尽时,晶须便不再发生轴向生长;气-固方式的作用主要是促进晶须棱面生长而使晶须变粗,对轴向生长几乎没有影响。

X-ray diffraction is one of the most common and efficient ways to measure a superlattice structure. This dissertation displays the detail results for characterization of Ge〓Si〓/Si superlattices by x-ray diffraction (including x-ray small angle diffraction and double crystal diffraction). It was found, when the growth temperature is lower, the intensities of xray small angle diffraction peaks are modulated by a periodical function, which indicates that both sets of interfaces of the superlattice is highly flat; when the growth temperature is higher, the diffraction peak intensities are simply decay with the increase of diffraction vector, which indicates that one set of interfaces is highly flat but another is not; when the growth temperature is very high, the diffraction peaks are reduced more rapidly, which indicates that both sets of interfaces are not ideal.
