Nettet2. mai 1978 · Extensive LEED intensity-energy data have been collected for a Si{100}(1 × 1)H surface and dynamical theory LEED calculations have been performed using an … Low-energy electron diffraction (LEED) is a technique for the determination of the surface structure of single-crystalline materials by bombardment with a collimated beam of low-energy electrons (30–200 eV) and observation of diffracted electrons as spots on a fluorescent screen. LEED may … Se mer An electron-diffraction experiment similar to modern LEED was the first to observe the wavelike properties of electrons, but LEED was established as an ubiquitous tool in surface science only with the advances in vacuum … Se mer Surface sensitivity The basic reason for the high surface sensitivity of LEED is that for low-energy electrons the interaction between the solid and electrons is especially strong. Upon penetrating the crystal, primary electrons will lose kinetic … Se mer • List of surface analysis methods Se mer In order to keep the studied sample clean and free from unwanted adsorbates, LEED experiments are performed in an ultra-high vacuum environment (residual gas pressure <10 Pa). Se mer Tensor LEED In LEED the exact atomic configuration of a surface is determined by a trial and error process where measured I–V curves are compared to … Se mer • LEED program packages • LEED pattern analyzer (LEEDpat) Se mer

Nettet8.1 Introduction and Background. Atomic layer deposition (ALD) is a chemical gas phase thin film deposition method based on sequential, self-saturating surface reactions [1–5]. Two or more precursor chemicals, each containing different elements of the materials being deposited, are introduced to the substrate surface separately, one at a time. http://www.ocivm.com/_low_energy_electron_diffraction.html
