Thin films of almost vertically-grown zinc oxide nanorods (ZnO NR) were prepared via a solvothermal method, and graphene quantum dots (GQDs) were synthesized by pyrolyzing citric acid. Various amounts of GQDs were loaded onto ZnO NR thin films by applying a dip-coating process for different times. Field emission scanning electron microscopy (FESEM), atomic force microscopy (AFM), transmission electron...
Si1-xGex (0≤x≤1) thin films were deposited by means of biased target ion beam sputtering at a low substrate temperature near 100 °C inside a vacuum chamber. The as-deposited films were all found to be amorphous and to be compressively stressed, and the magnitude of the compressive stress was found to decrease with increasing Ge content. Heat treatment for 30 min under vacuum conditions in the range...
