Abstract :
We present an extensive study about the formation of Ge nanocrystals by using two-step process deposition by a commercially UHVCVD system. We also investigate the growth duration effect on micro-Raman characterization in SiO2 matrix containing Ge-NCs. FTIR spectroscopy is employed to monitor the amount of various chemical bonds in SiO2 matrix embedded with Ge-NCs under various annealing temperatures. The C-V curves show the hysteresis indicating the charge storage. Furthermore, high temperature annealing effects are also presented and going to be discussed
