In this study, the nanomechanical damage was investigated on the annealed Si/SiGe strained-layer superlattices (SLSs) deposited using an ultrahigh-vacuum chemical vapor deposition (UHVCVD). Nanoscratch, nanoindenter, atomic force microscopy (AFM), and transmission electron microscopy (TEM) techniques were used to determine the nanomechanical behavior of the SiGe films. With a constant force applied,...
Highly semi-polar (101̅3) oriented and fine structural AlN films were successfully prepared on silicon substrate by rf magnetron sputtering in this research. The dependence of the nitrogen concentrations and the material characteristics of the films (crystalline structure and micro morphology) were investigated. The crystalline structure of the films was determined by X-ray diffraction (XRD) and the...
We investigated in this study structural and nanomechanical properties of zinc oxide (ZnO) thin films deposited onto langasite substrates at 200degC through r.f. magnetron sputtering with an r.f. power at 200 W in an 02/Ar gas mixture for different deposition time at 1, 2, and 3 h. Surface morphologies and crystalline structural characteristics were examined using x-ray diffraction (XRD), scanning...
Yellow peaches (Prunus persicu L. Batsch.) were stored under controlled atmospheres (CA) of 2%O 2 +5%CO 2 , 5%O 2 +10%CO 2 , 2%O 2 +10%CO 2 , 5%O 2 +5%CO 2 , and normal atmosphere at 2 °C, to investigate the effects of different concentrations of O 2 and CO 2 on the structure of a single sodium carbonate-soluble pectin...
