STRUCTURE AND SEMICONDUCTOR OPTICAL APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a germanium structure increasing a reduction effect of direct energy gap E0by tensile strain.

SOLUTION: The germanium structure has a germanium particle and a buried layer covering over the germanium particle for embedding the germanium particle, and the buried layer generates the tensile strain in the germanium particle in each direction of three crystal axes of the germanium particle.
