A thick film has a red shift of direct transition bandgap than thin films due to the strong interface interaction.
由于厚膜中存在较强的表面相互作用，厚膜的直接跃迁禁带宽与薄膜相比发生了红移。
The optical direct bandgap taking blue shift can be explain by quantum confinement effect effective mass approximate method.
针对其光学直接禁带宽度发生蓝移，使用量子限域和有效质量近似方法得到了解释。
