Abstract
基体上に歪んだ層を作製する新規の方法及び作製された層構造物の提供。
【解決手段】
この課題は、歪み層(2)を作製する方法において、
− 層(2)を基体(1)の上に配置しそして歪ませ、
− 歪んだ層(2)を構造化し、
− その層(2)を緩和し、
− 歪めるべき層(2)において方向転位を生じさせる
各段階を含むことを特徴とする、上記方法によって解決される。このようにして作製した層構造は三軸的に歪んだ層を有する。
Description
歪めるべき層を基体上に配置し、その際に該層は格子不整合によって歪められる。この層は例えばマスキングによって構造化される。該層は緩和される。この構造物の面の利用下に、歪めるべき層中で方向付け転位を生じる。
