New progress of studies on semiconductor materials

The strategic position and important role of semiconductor materials, as a core andfoundation of the information society, for development of national economic, national safetyand society progress are analyzed first in this paper. Then the present status and futureprospects of studies on semiconductor materials such as silicon crystals, III-V compoundsemiconductor materials and GaAs,InP and silicon based superlattice and quantum wellmaterials, quantum wires and quantum dots materials, microcavity and photonic crystals, materi-als for quantum computation and wide band gap materials as well are briefly discussed.Finally the suggestions for the development of semiconductor materials in our country areproposed. II-VI narrow and wide band gap materials, solar cell materials and organic materials foroptoelectronic devices etc. are not included in this article.
