In an ultrahigh vacuum chamber with a base pressure of 1 x 10-10 torr, we have used Low Energy Electron Diffraction and Temperature Programmed Auger to study the effect of adsorbates on the surface structure of Nb(111). That is, in O/Nb(111) systems, we observe the structure of the surface with LEED to see if any surface reconstruction occurs after annealing and analyze the structure.

The solution was gently concentrated at atmospheric pressure and 45 °C. With a minimum amount of diethyl ether left, the flask was connected to a sublimation tube cooled with dry ice, and the product was sublimed under vacuum (0.5 Torr) after the remaining diethyl ether had evaporated into a liquid nitrogen trap.

The thickness of thin film increases from 2337 to 3233 and the porosity of thin film increases from 29% to 36%, when the deposition pressure increases from 1.5 torr to 4.5 torr. Also, the refractive index decreases from 1.42 to 1.38 and the dielectric constant decreases from 2.01 to 1.9 when the deposition pressure increases from 1.5 torr to 4.5 torr.

Three samples with different Sb beam equivalent pressure of 0, 1.8×10-8and 6×10-8 torr are grown by molecular beam epitaxy. With increasing Sb beam flux, the room-temperature emission from the InAs QDs is blue shifted from 1323nm to 1295nm and the emission intensity is reduced.
我们成长三片不同Sb含量的InAsSb量子点，Sb分子束的等效压力(Beam Equivalent Pressure，BEP)分别为0、1.8×10-8、6×10-8，由PL量测得知随著Sb含量的增加，发光波长从1323nm蓝移至1295nm，显示量子点变小颗或应力变大的效应，这个现象亦导致了Sb量最多的样品基态和第一激发态离砷化镓导带较近，使得温度升高载子局限力较差。
Diffusion deposition loss was only 3.5% for 15 nm particles. When Pod was reduced to 5.4 Torr, nanoparticle diffusion loss was still low however inertial impaction loss was increased to 50%, which mainly occurs at the tube wall downstream of the orifice. Increasing the inner diameter of the outlet tube was found to reduce particle loss due to inertial impaction. For example, increasing inner diameter from 6.2 mm to 25 mm, particle loss was reduced to zero.
当下游压力降低至5.4 Torr时，奈米微粒扩散损失仍很小，但惯性冲击损失会高达50%，主要发生在流孔板下游管壁上，解决方法为加大下游管径，如将下游管径从6.2 mm增加至25 mm，则奈米微粒惯性冲击损失会降为零。
