[en] The main physical properties of amorphous systems are examined and an general overview of this subject as a matter of active research is presented. The amorphous systems contain a rich phenomenology without a reasonable explanation up to now and can yield a sort of technological applications, this represents a stimulus for scientists and technologists.

[en] In this work, it is studied the formation and characteristics of the amorphous - polycristalline silicon isojunction barrier. (A.C.A.S.)

[en] Twenty-two papers were presented at the 21st colloquium on metallurgy of amorphous alloys and materials. They deal with the applications, the various types, the preparation methods, the structure, the magnetic and thermodynamic properties and the structure defects of the amorphous materials

[en] It was developed a simple system but realistic to obtain the density of states of amorphous binary alloys involving transition metals. (A.C.A.S)

[en] Full Text: The termophysical properties of fibroins of natural polymer are investigated. It is established, that at injecting of antioxidants N-(3,5-ditret-buty-4-hydroxyfenil) salicylaldimin into the structure of fibroins, by additional fertilizing of caterpillars by last-named amorphous sites increase and thus the stability of silk to external influences raises, i.e. the stabilization occurs due to sewing action of antioxidant

[en] Transmission sputtering yields of single and polycrystalline gold foils have been measured as a function of thickness in the range 250--5000 A for bombardments with 560-keV Bi, 400-keV Ag, 200- and 400-keV Ar, and 50-keV He ions. Good agreement is found between the yield curves for polycrystalline and single-crystalline targets oriented in a high-index (random) direction. Calculated distributions of energy deposition in an amorphous target compare well with regard to the position of the maximum in the sputter yield. Absolute yields in the vicinity of the peak are generally in better agreement with yields calculated by Monte Carlo simulation for finite targets than with yields calculated on the basis of transport theory in an infinite solid. Compared with theory, all measured yield curves exhibit considerable enhancement at great depths. Sputter-yield distributions for a beam of 560-keV Bi ions along < 100 > are in qualitative agreement with channeling theory. From a comparison with the random sputter-yield distributions, it can be concluded that channeling of such heavy projectiles causes a relatively minor reduction (< or approx. = 40%) in the total amount of energy that goes into nuclear motion

[en] It is developed a simple formalism which allows us to perform a self consistent non-parametrized calculation in a non-periodic system, by finding out the thermodynamically averaged Green's function of a cluster Bethe lattice system. (Author)

[en] Real Space renormalization techniques are applied to study different disordered systems, with an emphasis on the under-standing of the electronic properties of amorphous matter, mainly semiconductors. (author)
