Using Auger Electron Spectroscopy (AES), Scanning Tunneling Microscopy/Spectroscopy (STM/STS) and Low Energy Electron Diffraction (LEED), we report an in-situ study of amorphous magnesium silicide (Mg2Si) ultra-thin films grown by thermally enhanced solid-phase reaction of few Mg monolayers deposited at room temperature (RT) on a Si(100) surface. Silicidation of magnesium films can be achieved ...
Porous silicon samples have been reduced in nanometric particles by a well known industrial mechanical process, the ball grinding in a planetary mill; the process has been extended to crystalline silicon for comparison purposes. The silicon nanoparticles have been studied by X-ray diffraction, infrared spectroscopy, gas porosimetry and transmission electron microscopy. We have estimated crystal...
Compared to other techniques of propagation, grafting is the most successful and feasible technique for asexual propagation of walnut plants. There is little information about graft union formation in walnut. Therefore, the objective of this study was to evaluate histological events during graft union formation in Juglans regia L. cv. Chandler scions when minigrafted on the one-year-old seedlin...
hazelnuts are usually propagated by suckers or layering. however, other methods of propagation have been tested with variable results. grafting is a method that has a few advantages such as fast multiplication rate, earlier fruiting and reducing sucker removal cost on specific rootstocks. unfortunately, grafting is difficult due to slow formation of callus in hazelnuts. here, we report the hypo...
Mango is one of the most important tropical fruits grown in southeast provinces of Iran (Sistan Baluchestan & Hormozgan). Due to the favorable coastal climate conditions in the region mango is extensively grown in these areas. This experiment was carried out at the tropical fruit research station of Bahokalate in Sistan Baluchestan province between 1997 and 1998, using 8-month-old seedlings rai...
Abstract The parametrization of the nanostructures covering energy harvesting (EH) devices play an important role in maximizing exploitation light and so does selection best suitable fabrication measurement methods. optical inspection periodic cylindrical for EH is a challenging task both manufacturers metrologists. In this paper we present process nanowires (NWs) along with non-optical techniq...
Since about 1982 new high resolution and high precision measurement methods have been developed whereas these methods can be used especially for the evaluation of surface topography in the nanometric range. Results of a series of experiments are analysed and discussed. General conclusions can be drawn as very often obtained scanning images looking like atoms topography structure have been mis...
