Abstract. In our previous paper  we have presented a simple theoretical model of the description of the low energy electron diffraction LEED by a thin film treated as a system of a few monoatomic layers parallel to each other and evaporated on a : K.
Stachulec. A simple dynamical approach to the description of the low energy electron diffraction (LEED) intensity is presented using the quantum field methods developed in thin film theories [1, 2, 5].
The scattering amplitude of the electrons scattered by the metallic thin film is expressed in terms of the surface electron density modulated by lattice vibrations of the atoms Author: K. Stachulec.

 KRŠJAK, V.: Potential of Positron Annihilation Lifetime Spectroscopy in Microstructural Study of Nuclear Reactor Steels. In: Journal of Electrical Engineering. - ISSN Thin iron films (80 nm) were firstly amorphized by boron implantation and subsequently irradiated with nitrogen ions in dose range 1** ions/cm2.
Energy and current density of implantation were 20 keV and A/cm2 respectively. Nevertheless, in thin films, in spite of the small amount of thickness and the small amount of damage deposited by self-ions, very large loops were detected, even larger than – nm distributed homogeneously within the material (Figure 16c and d).

Probimide and SiO2 thin films were deposited to aid the LT lift-off process before the pattern generation. Interdigitated structure was achieved by photolithography and reactive ion etching.
Pd Schottky metal was deposited at a substrate temperature near 77 K using a lift-off technique. 5 Thin-Film Materials and Processes Thin films versus bulk materials Physical vapour deposition (PVD) Evaporation and molecular beam epitaxy.
Recently, a new approach based on intercalation of atomic layers of MI, referred to as magnetic extension, was proposed to realize strong MPE [2D Mater. 4, ()]. Motivated by this proposal, here, we study a magnetic extension system prepared by molecular beam epitaxy growth of MnSe thin films on topological insulator (Bi,Sb)2Te3.
