项目摘要
We successfully fabricated single-crystalline semiconductor microspheres that have surfaces with atomic-level smoothness. These microspheres were formed by performing laser ablation in superfluid helium to create and moderately cool a melt of the anisotropic semiconductor material. This novel method provides cooling conditions that are exceptionally suited for the fabrication of single-crystalline microspheres.We also successfully demonstrated optical manipulation of semiconductor nanoparticles, CuCl, ZnO, and CdSe in superfluid helium that shows low temperature, negligibly small viscosity, and high thermal conductivity. In the manipulation process we can simultaneously sort the size of the particles, because the radiation force is strongly dependent on the resonant condition of the confined excitons in the particles, which is determined by the size. In other words, we succeeded in the selection of the energy levels of the semiconductor nanoparticles.
我们成功地制造了具有原子水平平滑度的表面的单晶半导体微球。这些微球是通过在超流体氦气中进行激光消融来形成的,以创建和中等冷却各向异性半导体材料的融化。这种新颖的方法提供了非常适合于制造单晶微球的冷却条件。我们还成功地证明了对半导体纳米颗粒,CUCL,ZnO和CDSE的光学操纵,在超富浮雕的氦气中显示出低温,显示低温,忽然较小的粘度和高温电导率。在操纵过程中,我们可以同时对颗粒的大小进行排序,因为辐射力很大程度上取决于粒子中受约束激子的谐振条件,这取决于粒子的大小。换句话说,我们成功地选择了半导体纳米颗粒的能级。
