Abstract: 
Semiconductor nanostructures and microstructures are currently attracting tremendous interest due to their comprehensive applications in nanoscale and microscale technologies. To improve the function of nanodeives, strain engineering has long been an important approach which was used to tune the band structure and vary the properties of semiconductors. However, the traditional strain engineering is mainly limited to local strain or homogeneous strain effect , which always accompany with high strain-gradient, especially in flexible nanodevice. In this project, based on first-principle DFT calculations, we will investigate the effect of strain-gradient on the energy band gap in nanowire.\n
