高手帮忙给翻译翻译呵，十分感谢！！ 自己好好修改一下：As III-V compound semiconductors.AlAs has excellent physical properties，is widely used in technology，so in recent years and people concerned about their nature，especially the high temperature and pressure characteristics.This year，sphalerite Structure of AlAs has been studied extensively，because it is not only important electronic and optoelectronic materials，and is making heterostructures，superlattices and quantum wells of the important components.study the electronic structure of these crystals，dielectric and elastic properties，can Semiconductor development of new materials provide a theoretical basis and experimental guidance.Because of the difficulty by chemical and physical vapor deposition and high-quality high-pressure synthesis of large single crystal，Therefore，the medium on the charge of these semiconductor materials elastic properties of the lack of experimental data.To help understand and control these materials，dielectric and elastic 。
