Mechanical Stress Evolution in Polycrystalline Ge Thin Films Under MeV Ion Irradiation
Advanced Materials Interfaces, EarlyView.Irradiation of polycrystalline Ge thin films with 1.8 MeV Au ions alters residual stress through defect generation and lattice expansion. Increasing fluence drives progressive lattice disorder and eventual amorphization. Polycrystalline Ge resists amorphization longer than crystalline Ge, as grain boundaries facilitate defect diffusion, significantly ...

Age-dependence of the average and equivalent refractive indices of the crystalline lens
, 2014 Lens average and equivalent refractive indices are required for purposes such as lens thickness estimation and optical modeling. We modeled the refractive index gradient as a power function of the normalized distance from lens center. Average index along

Exploring the Potential of Microwave Annealing for Enhancing Si‐based GeSn Lasers
Advanced Materials Technologies, EarlyView.We explore low‐thermal‐budget microwave annealing to enhance the performance of group‐IV GeSn lasers on Si. Microwave annealing under optimal conditions can simultaneously relax unwanted compressive strain and enhance the material quality of the GeSn active layer, thereby reducing the threshold and increasing the laser operating temperature.
