摘要: 在各向同性弹性理论的假设下,运用解析方法对量子线结构进行分析,通过对格林函数的积分运算,得到无限大基体内横截面为梯形的量子线结构的应力和应变场的解析解.另外,还讨论了量子线横截面的高度和初始失配应变变化对应变分布的影响.

Abstract: Based on the isotropic elastic theory and using the integral operation for Green’s function, analytical solutions of the stress and strain fields inside and outside a trapezoidal cross-section quantum-wire structure in an infinite matrix are obtained. The influences of variable height for the quantum wire cross-section and initial mismatch strain on the strain distribution are discussed.

Key words: analytical solution, initial mismatch strain, quantum-wire, stress and strain distribution
