摘要： When a Si single crystal 8 is pulled up from a melt 6 received in a crucible 2, the state of eddy flows generated in the melt 6 is judged from the temperature distribution of the melt at the surface. According to the result of judgement, the gas, i.e. N.sub.2, Xe or Kr, which causes extraoridnary deviation in the density of a melt 6 is added to an atmospheric gas, so as to keep the eddy flows under unstabilized condition. The effect of said gas is typical in the case of crystal growth from the melt to which a dopant such as Ca, Sb, Al, As or In having the effect to suppress the extraordinary deviation in the density is added. Since the single crystal is pulled up from the melt held in the temperature-controlled condition at the surface, impurity distribution and oxygen distribution are made uniform along the direction of crystal growth. A single crystal obtained in this way has highly-stabilized quality.
摘要翻译：当将Si单晶8从容纳在坩埚2中的熔融物6拉出时，根据表面的熔体的温度分布来判断在熔体6中产生的涡流的状态。根据判断结果，将气体，即N2，Xe或Kr，其引起熔体6的密度的异常偏差加到大气中，以保持涡流处于不稳定状态。在来自熔融体的晶体生长的情况下，所述气体的效果是典型的，在该熔体中添加了具有抑制密度特别偏差的作用的诸如Ca，Sb，Al，As或In的掺杂剂。由于单晶被从保持在表面的温度控制条件下的熔体中拉出，所以杂质分布和氧分布沿晶体生长方向均匀。以这种方式获得的单晶具有高度稳定的质量。

摘要： The present invention provides a nanowire production method that is simpler than conventional nanowire production methods, and that makes it easier to control the size and shape of the nanowires by using a technique completely different from the conventional ones. A powder particle containing a metal element is divided into nanometer-size wires containing the metal element by irradiating a suspension of the powder particles with a femtosecond laser. The present invention also makes it possible to divide the nanometer-size wires thus formed into nanometer-size particles containing the metal element by irradiating further the nanometer-size wires with the femtosecond laser.

摘要： The density of a melt precisely represents the stability of the melt, so that the initiation of pulling-up operation can be determined on the basis of the changing rate of the density. The pulling-up operation may be started when the density becomes constant, or when the changing rate of the density with respect to the temperature becomes smaller. Since the melt or clusters do not include different minute structures, an obtained single crystal is of high quality free from minute faults or dislocations.
