The La_(0.7)Sr_(0.3)MnO_3 bulk is rhombohedral at room temperature with the pseudocubic parameter a of 3.873 A and a large distorted pseudocubic angle α of 90.26 °; when it grown at the cubic substrates, besides the elastic normal strains due to the lattice mismatch between the film and substrate, there is a further type of distortion in coherent LSMO films, namely, elastic shear.

首先讨论锰氧化物外延膜的厚度与角度畸变的关系；由于LSMO具有菱形对称性，当晶体结构转变为赝立方时，其赝立方夹角为90.26°。

ABSTRACT In this dissertation, the device physics, optimum structures, material design and growth and fabrication of Si/SiGe heterojunction bipolar transistor , as well as the physical parameter models for pseudomorphic Si〓Ge〓 layers grown on Si substrate have been studied systematically.
