A modified horizontal gradient-freeze approach with quasidouble parabolic temperature profile has been developed for growing GaAs single cryatals. Using this approach, the dislocation-free Si-doped crystals with <111>B and <211> B orifented seeds have been grown successfully. It has been found that the solid-liquid interface is slightly convex and nearly perpendicular to the grovth direction during the growth process, indicating good thermal symmetry in the growth region, and so some deficiencies...

A modified horizontal gradient-freeze approach with quasidouble parabolic temperature profile has been developed for growing GaAs single cryatals. Using this approach, the dislocation-free Si-doped crystals with <111>B and <211> B orifented seeds have been grown successfully. It has been found that the solid-liquid interface is slightly convex and nearly perpendicular to the grovth direction during the growth process, indicating good thermal symmetry in the growth region, and so some deficiencies due to the inclined and slightly concave interface in conventional horizontal Bridgman growth could be avoided. Some other features in this approach are also discussed. It is suggested that the effectiveness of dopant Si for reducing the dislocation density of the crystals may be related to the interaction between SiGaVGa complexes and dislocations.

本文提出具有准双抛物线温度分布的水平梯度凝固法生长GaAs晶体.利用此法成功地生长了取向〈111〉B和〈211〉B的掺Si无位错GaAs单晶.晶体在生长过程中,生长界面微凸,与生长方向近乎垂直,表明生长区热对称性良好,从而避免了沿用的水平Bridgman法的一些弊端.文中对该法的其它一些工艺特点也作了详尽的论述.此外,认为掺Si降低位错密度的作用,可能与形成的Si_(G?)V_(G?)络合物与位错的交互作用有关.

Longitudinal temperature distribution expressed by T_f(z)atthe crucible wall in vertical gradient freeze growth strongly influences theinterface.convexity By means of zero setting for convexity of isothermal itis convenient to determine the convexity distribution along the crucible axisby the sign and absolute value of (?)~2T_f(z)/(?)z~2.the function T_f(z)can beobtained by measuring temperature at the outside wall of crucible by using thermocouples.

本文证明了静态温梯法中坩埚侧壁处的纵向温度分布 T_(?)(z)的函数形式,对坩埚中固液等温面的凸度有着重要影响作用。指出通过温度场“调零”过程后,利用(?)~2T_(?)(z)/(?)z~2的符号和大小来判断坩埚中固液面凸度分布情况。并且认为在实际工作中T_(?)(z)可以用热电偶在坩埚外壁处测量而得到。

Both analytical methods and numerical techniques showed thatthe instantaneous cooling rate causes the interface to become increasingly con-cave in Vertical Gradient Freeze Method.Dimensionless number D_e=R~2_ρc_pC./〔k(T_h-T_o)〕is defined to express the extent that the interface becomesmore concave arised from instantaneous cooling rate.

本文用解析和数值计算的方法,证明了静态温梯法晶体生长中,瞬时降温速率有使固液等温面下移且变得更凹的倾向,定义了降温显热数 De=R~2pc_pCo/k(T_h-T_c),用来表征瞬时降温速率使固液等温面变凹的程度。
